Explanation: Although the object detection tool did not recognize the camera with high confidence, the camera is still visually discernible in the image. The tool may struggle due to the protective cover or angle, but it is visibly present.

Answer: 0


Explanation: The object detection tool identified the smart connector pins with a very low confidence score of 0.0299, which is below the threshold of 0.1. A low confidence score typically indicates that the detection algorithm is inconclusive about the presence of the features. Additionally, from the image itself, while there are small dots visible at the bottom edge of the iPad, their presence isn't clearly or prominently highlighted. Therefore, it can be inferred that the smart connector pins are not visibly distinct or identifiable without closer inspection.

Answer: 2


Explanation: Although the camera on the iPhone is physically visible in the image, the object detection tool has given it a very low confidence score of 0.024. A score below 0.1 indicates that the detection is not reliable or significant enough to consider it as 'detected' by the tool.

Answer: 2


Explanation: Although the object detection tool did not recognize the speaker with high confidence (0.042634820826755154), visually inspecting the image reveals a series of small perforations on the bottom front of the phone. These perforations are characteristic of a speaker grill. However, their small size and the lack of a clear visual cue (e.g., no label or icon) make it harder to identify without prior knowledge of the phone's design.

Answer: 1


Explanation: Considering the output from the object detection tool with a confidence score of 0.028196906914948246 (below the threshold of 0.1), it suggests that the space bar was not reliably detected. This low confidence likely indicates that the space bar is either not visible or very difficult to see in the image.

Answer: 2


Explanation: Although the object detection tool did not recognize the rubber feet with high confidence, the rubber feet are clearly visible in the image. It is possible for detection tools to miss features that are easily identifiable to the human eye due to issues like texture, lighting, or contrast. The human eye can easily spot those rubber feet at the corners of the laptop.

Answer: 0


Explanation: Although the object detection tool did not recognize the touchpad with high confidence (0.040570024786308244), the visual inspection of the image shows that a touchpad is clearly visible beneath the keyboard of the laptop. Automated detectors may sometimes fail to identify objects accurately, especially when visual context is straightforward for a human observer.

Answer: 0


Explanation: Although the object detection tool did not recognize the headlight with high confidence (0.008906138645511763), this does not necessarily mean the headlight is not present in the image. The tool might have failed to detect it accurately due to lighting, angle, or algorithm limitations. However, a human observer can clearly see the illuminated headlight on the train in the image.

Answer: 0


Explanation: Although the object detection tool did not recognize the arrow keys with high confidence (confidence < 0.1), manually inspecting the image shows they are present on the right side of the keyboard. These keys are in a standard arrow configuration and are clearly visible to the human eye. The detection tool may have failed due to lighting, shadows, or resolution issues, but this does not mean the keys are absent.

Answer: 0


Explanation: Although the object detection tool did not successfully identify the driver window with a confidence above 0.1, manually inspecting the image shows clearly visible driver windows on the front of the train locomotive.

Answer: 0


Explanation: 尽管物体检测工具以0.03038839147769633的置信度识别出摩托车的前部，但根据要求，当置信度低于0.1时，即视为未检测到。从图像内容来看，摩托车的前部确实包含了一个部分可见的 handlebar。因此，结合图像内容和工具检测的实际情况，可以认为 handlebar 可见但较难辨认。

Answer: 1


Explanation: Considering the confidence level obtained from the object detection tool, which is 0.015008942428035488, this value is below the threshold of 0.1. Therefore, even though the scrolling wheel might be physically present, the tool classifies it as undetected due to the low confidence score.

Answer: 2


Explanation: Although the home button is clearly visible to human eyes, the object detection tool's confidence score of 0.0094 falls below the 0.1 threshold, indicating it wasn't detected. This can happen due to factors like lighting, angle, or the tool's limitations. However, based on human perception, the home button is visible.

Answer: 0


Explanation: Although the ground pin holes are clearly visible to the human eye in the image, the object detection tool has a very low confidence score of 0.0144, which is below the detection threshold of 0.1. This implies that the tool did not reliably detect the ground pin holes.

Answer: 1


Explanation: Although a screw is observable to the human eye in the image, the object detection tool's confidence level of 0.0111 (which is less than 0.1) implies that the tool did not reliably detect the screw. Hence, from the tool's perspective, it was not detected.

Answer: 2


Explanation: Although the object detection tool did not recognize the screw with sufficient confidence, the screws are clearly visible to the human eye. The confidence level from the tool might be low due to factors like lighting, angle, or other image characteristics, but it does not affect the actual visibility in the image. Therefore, there is a high confidence (clearly visible) of presence of screws.

Answer: 0


Explanation: Although the object detection tool did not recognize the drain hole with high confidence (0.03024354685871036, which is below the threshold of 0.1 for detection), the drain hole is visually apparent in the image. The tool's low confidence may be due to factors such as lighting, the metallic texture of the sink, or the design of the drain cover, making it harder for the model to recognize the specific pattern. Nevertheless, a human observer can clearly identify the drain hole in the center of the sink.

Answer: 1


Explanation: Although the object detection tool did not recognize the overflow holes with high confidence, the visual evidence in the image shows two small holes near the rim of the sink, which are identifiable as overflow holes. The low confidence might be due to the tool's limitations in recognizing small features or specific objects in certain contexts.

Answer: 0


Explanation: Although the tracks are clearly visible to the human eye, the confidence level from the object detection tool is 0.04803504041012977, which is below the threshold of 0.1 for detection. This indicates that the model failed to confidently detect the tracks, despite their visibility.

Answer: 2


Explanation: Although the pressure gauge needle is clearly visible to a human observer in the image (pointing to the green zone on the gauge), the provided object detection tool has reported a very low confidence score of approximately 0.032. Since this score is below the 0.1 threshold specified for detection, the tool effectively considers the object 'undetected' or not reliably present.

Answer: 2


Explanation: Based on the provided object detection tool results, the zipper tag has a confidence score of approximately 0.023. Since this value is significantly below the 0.1 threshold for detection, the tool confirms that the zipper tag is not visible or detectable in the image.

Answer: 2


Explanation: Upon reviewing the object detection tool's output, it indicates a very low confidence (0.045494373648778015) for the existence of a ruler. A confidence below 0.1 implies that the object wasn't confidently detected. Furthermore, visually inspecting the image confirms that there is no ruler present.

Answer: 2


Explanation: Although the front wheel of the wheelchair is physically visible in the image, the question specifically asks to evaluate the situation based on the provided object detection tool's output. The tool reported a confidence score of approximately 0.0087 for the 'front wheel'. Since this value is significantly less than the 0.1 threshold specified in the instructions, the object is considered undetected by the system.

Answer: 2


Explanation: The image displays a mechanical tray balance scale, which operates on the principle of comparing masses against a fulcrum rather than using a dial for measurement. An object detection tool identified a potential dial with a confidence score of 0.036, which is significantly below the 0.1 threshold for a true positive detection, thus confirming that no dial is actually visible in the image.

Answer: 2


Explanation: Although the tuning pegs are clearly visible to a human observer, the provided object detection tool has a very low confidence score (0.0306) for detecting tuning pegs. In the context of object detection, a confidence score below the standard threshold (here specified as 0.1) is considered an indication that the object was not successfully detected or is 'undetected' by the system. Therefore, based on the tool's output, the tuning pegs are treated as not visible.

Answer: 2


Explanation: Although the f-holes are clearly visible to the human eye in the image, the specific object detection tool used has assigned a very low confidence score (0.01296...) for detecting the f-hole. According to the user's criteria, a confidence score below 0.1 indicates that the object was effectively not detected by that specific tool.

Answer: 2


Explanation: Although the tuning pegs are physically present and visible in the image, the specific object detection tool used has assigned a confidence score of approximately 0.033 to them. In the context of detection, a confidence score below the standard threshold of 0.1 indicates that the tool failed to confidently identify the objects, effectively categorizing them as undetected.

Answer: 2


Explanation: The image clearly shows a string instrument with a long, black fingerboard on the neck, which is visible above the strings. Even though the object detection tool reported a confidence of 0.027, which is low, visually, the fingerboard is unmistakable in the image. The low confidence is likely due to a technical limitation of the tool, not the actual invisibility of the fingerboard. Therefore, the fingerboard is clearly visible.

Answer: 0


Explanation: Although the strings are physically present and visible to a human observer, the object detection tool detected them with a confidence score of approximately 0.014. According to the user's provided rule, a confidence score less than 0.1 indicates that the object was not successfully detected by the tool. Therefore, based on the tool's output status, the strings are considered undetected.

Answer: 2


Explanation: The provided object detection tool report indicates that the objective lens was detected with an extremely low confidence score of 0.0405, which is below the valid threshold of 0.1. Consequently, according to the provided criteria, the tool did not successfully detect the objective lens.

Answer: 2


Explanation: The confidence score of 0.018 provided by the object detection tool indicates that the model did not reliably detect a reflector. A confidence level significantly below the 0.1 threshold, as noted in the prompt, implies 'undetected'. Therefore, based on the detection results provided, a reflector is considered not visible.

Answer: 2


Explanation: Although the object detection tool reported a very low confidence score, human visual inspection confirms the presence of the coarse focus knob on the microscope's arm. The knob is a standard, prominent mechanical part of the device, and its features are clearly distinguishable in the image.

Answer: 0


Explanation: The fine focus knob is technically present in the microscope image, positioned as the smaller inner knob of the coaxial focus controls. However, the provided object detection tool identified this specific part with a very low confidence score of approximately 0.029. Since the instructions state that a confidence less than 0.1 means the object is undetected, the correct classification based on the provided tool's data is that it is not visible to the detector.

Answer: 2


Explanation: The provided object detection tool report indicates that no stage clip was successfully detected with a confidence higher than the 0.1 threshold (0.009... is well below). Visually, the microscope features a mechanical stage where 'clips' are often integrated or moved with the stage controls, rather than being separate, obvious spring-loaded clips attached to the corners. Thus, based on the tool's finding and the specific design of this mechanical stage, a distinct 'stage clip' is considered not visible.

Answer: 2


Explanation: The image clearly shows the two oval handles with finger holes at the bottom of the scissors. While the object detection tool might have produced a low confidence score due to specific technical reasons or noise, visually, the finger holes are an obvious and prominent feature of the object depicted.

Answer: 0


Explanation: The image contains a comb, not human or animal features. Although the object detection tool found a very low confidence score for 'teeth' (0.003), this is not a valid detection. The confidence is well below the threshold of 0.1, which indicates that the detection is unreliable or erroneous. Therefore, there are no visible teeth in the image.

Answer: 2


Explanation: The image shows a plain, cylindrical cup or container with a smooth, uniform surface. There are no protrusions, loops, or attachments that function as a handle. Furthermore, the object detection tool provided a confidence score of 0.0046 for a handle, which is far below the 0.1 threshold, confirming that no handle was actually detected.

Answer: 2


Explanation: Although the rim is physically present and visible in the image as the top edge of the mug, the user's provided context explicitly states that an object detection tool has identified it with a very low confidence (0.0106). The user's criteria define a confidence score below 0.1 as 'undetected'. Therefore, based strictly on the provided detection result, the system considers the object to be undetected.

Answer: 2


Explanation: Although the temples are partially visible in the human eye view, the specific object detection tool used has assigned a very low confidence score (0.0458...) for detecting the temple arm. Since the criteria states that a confidence less than 0.1 means undetected, based on the tool's output provided, the object is considered undetected.

Answer: 2


Explanation: The object detection tool identified the nose pad with a very low confidence of 0.020277189609878944. In object detection, a confidence score below the standard threshold of 0.1 (or 10%) is generally considered an indication that the object is not reliably detected or is effectively undetected by the system.

Answer: 2


Explanation: The visual inspection of the image confirms there are no hands present on the clock face. The object detection tool's low confidence score of 0.036 (which is well below the 0.1 threshold for a valid detection) aligns with this observation, further validating that the object is not present.

Answer: 2


Explanation: Upon visual inspection of the image, the clock face is plain white and features no markings, numbers, or indices for the hours or minutes. The detected confidence of 0.025 (approx 0.0249) for 'dial numbers' is extremely low, well below the 0.1 threshold, indicating that the object was not successfully detected or is essentially non-existent. Therefore, the dial numbers are not visible.

Answer: 2


Explanation: Upon visual inspection of the image, only the plugs and power strips themselves are depicted. The flexible cords that typically connect the plug to the power strip are absent from the scene. The object detection tool's very low confidence (0.022) confirms that no cord is present or identifiable.

Answer: 2


Explanation: Upon visual inspection of the image, there are no power plugs present. The image displays two power strips (also known as extension cords or multiplexers) which have empty sockets (outlets). The object detection tool's finding with a very low confidence of 0.0207 likely indicates a false positive or the detection of a socket hole rather than an actual plug. Since no plug is inserted into the sockets, none are visible in the picture.

Answer: 2


Explanation: Upon visual inspection of the object in the image, it appears to be a wall-mounted water tap without a visible handle, lever, or wheel. The object detection tool reported a very low confidence score of approximately 0.03, which is well below the 0.1 threshold for detection. This numerical output confirms the visual observation that no handle is present and detectable in the image.

Answer: 2


Explanation: Although the image visually contains tires, the specified object detection tool reported a confidence score of approximately 0.029 for detecting a tire. Since the confidence threshold for a valid detection is given as 0.1, the tool effectively 'did not detect' the tire based on its own parameters.

Answer: 2


Explanation: The image shows a larger fire extinguisher, likely a wheeled model, rather than a portable handheld one. These types of extinguishers typically lack the small squeeze lever found at the top of the handle, instead using a different mechanism. The low confidence score of 0.03 from the object detection tool further supports that there is no squeeze lever visible.

Answer: 2


Explanation: The Kettle object detection tool reports a confidence of 0.005 for the spout, which is significantly below the 0.1 threshold for a valid detection, classifying it as undetected. However, visual inspection of the image confirms that the kettle does have a spout; it is simply located on the opposite side of the handle and is obscured from this viewing angle, making it not visible to the viewer or the detection algorithm in this specific frame.

Answer: 2


Explanation: The Kettle, despite its small confidence score of 0.012583771698118779 (which is below the 0.1 threshold for detection), has a clearly visible black handle on its right side. The low confidence score likely indicates an issue with the detection algorithm rather than the object's invisibility.

Answer: 0


Explanation: Although the handlebar components are physically present on the bicycle, the object detection tool assigned a confidence score of 0.0487, which is below the 0.1 threshold required to consider the object detected. Therefore, for the purpose of this evaluation based on the tool's output, the handlebar is considered undetected.

Answer: 2


Explanation: Although the pedal is physically present and visible to the eye in the image, the object detection tool has identified it with a very low confidence score of 0.0169. In the context of object detection, a confidence score below the standard threshold (here defined as 0.1) typically indicates that the object was not successfully detected or is indistinguishable from the background to the model. Therefore, based on the provided detection tool's output, the pedal is considered undetected.

Answer: 2


Explanation: Upon examining the provided image, the saddle (seat) is located at the rear of the bicycle frame. The image is cropped or angled such that the rear section of the frame and the seat post are not visible. The highest point visible at the rear is the top tube connecting to the seat stay, but no saddle is apparent. The detection tool's very low confidence (0.01) further supports that there is no significant saddle feature present in the image frame.

Answer: 2


Explanation: Based on the visual inspection of the image, there is no visible indicator light on the kettle. The object detection tool also reported a very low confidence score (0.039) for detecting an indicator light, which is below the 0.1 threshold for a reliable detection, confirming that no indicator light is present or reliably identifiable.

Answer: 2


Explanation: An object detection tool attempted to find a switch but returned a very low confidence of 0.01457131032100732. A confidence score below 0.1 is considered undetected, which confirms that no switch is reliably identifiable in the image. Furthermore, a visual inspection reveals the absence of any physical switches or controls on the fan.

Answer: 2


Explanation: Based on the provided image analysis and the object detection tool's output, the keyboard is not clearly visible. The detection confidence for the keyboard is extremely low (approximately 0.034), well below the 0.1 threshold for a positive detection. The visual evidence confirms that the laptop is angled such that the keyboard surface is turned away from the camera and not in view.

Answer: 2


Explanation: Although the object detection tool returned a confidence score of 0.0137, which is below the 0.1 threshold for a valid detection, the handles are visually very prominent and obvious in the image. The low confidence score appears to be a result of the tool's error or misidentification, not an absence of handles. Therefore, the handles are 'clearly visible' to a human observer.

Answer: 0


Explanation: Although the object detection tool reported a low confidence score of 0.028, visual inspection of the image confirms that the wheels are clearly visible. The tool's confidence score appears to be incorrect or a false negative for this specific object, possibly due to the wireframe structure causing confusion in the algorithm. Therefore, the answer remains that the wheel is clearly visible.

Answer: 0


Explanation: Based on the provided image analysis and the object detection tool's output, the propeller is not visible. The detection confidence was extremely low (0.02), well below the 0.1 threshold for a valid detection, indicating the propeller is indeed not present in the frame.

Answer: 2


Explanation: The vertical stabilizer is clearly visible on the aircraft in the image. Confidence values from object detection tools can be affected by specific criteria such as occlusion, blur, or angle. However, the visual evidence in the provided image shows an unobstructed and clear view of the vertical stabilizer.

Answer: 1


Explanation: The provided object detection tool report indicates that no windows were detected, as the single detection found had a confidence score of 0.043, which is below the 0.1 threshold required for a positive detection. This aligns with the visual evidence in the image, where the side profile of the aircraft obstructs the view of the pilot and co-pilot cockpit windows, making them not visible.

Answer: 2


Explanation: The confidence score of 0.0469 provided by the object detection tool is very low, falling below the 0.1 threshold mentioned for valid detection. Therefore, according to the tool's assessment, the horizontal stabilizer is considered undetected.

Answer: 2


Explanation: Although the user's object detection tool reports a very low confidence (0.010) for the rear-view mirror, suggesting it might be undetected, a visual inspection of the image clearly shows the rear-view mirror mounted on the windshield at the top center of the frame. Therefore, it is present and clearly visible, making the low detection confidence an error by the tool.

Answer: 0


Explanation: Although the upper part of the steering wheel housing is visible in the lower-left, the object detection tool failed to identify it with high confidence (0.0023, well below the 0.1 threshold). This suggests the visible portion is too inconspicuous or ambiguous (lacking the typical rim) to be reliably classified as a 'steering wheel' by an algorithm, making the detection effectively a non-detection for practical purposes.

Answer: 2


Explanation: The bread slots are clearly visible in the image. The low confidence detected by the object detection tool (0.013) is likely due to the tool misclassifying the top surface or the specific view of the slots, as the slots are a prominent feature of this specific toaster model shown in the image. The slots are the openings on the top surface designed to receive bread.

Answer: 0


Explanation: Upon examining the provided image of the KitchenAid toaster, there is no visible lever. The lever that typically lowers the bread into the toaster slots is usually located on the side or front, but this specific view does not display it. The user's mention of an object detection result with very low confidence (0.019) further supports that the lever was effectively not detected or is absent from view.

Answer: 2


Explanation: Based on the provided object detection tool results, the detected 'engine' has a confidence score of approximately 0.03. Since a confidence score below 0.1 is considered undetected, the tool determined that there is no visible engine in the image.

Answer: 2


Explanation: Although the object detection tool returned a confidence score of 0.025, which is below the 0.1 threshold for detection, the vertical stabilizer (the main tail fin) is clearly and distinctly visible to the human eye in the image. The tool's output appears to be a false negative or an error in this specific case.

Answer: 0


Explanation: Although the object detection tool returned a low confidence score of approximately 0.03, the horizontal stabilizer is physically present and clearly visible in the image. It is the small wing structure on the tail section of the aircraft, located just behind the main fuselage and below the vertical fin. Visual confirmation overrides the tool's low confidence in this case.

Answer: 0


Explanation: The image displays the side profile of a United Airlines Boeing 777 aircraft. The cockpit is located at the nose of the plane. Due to the angle of the photograph (viewing from below and slightly to the side, with the nose pointed somewhat away), the front face of the aircraft where the cockpit windows are typically located is not visible. The object detection tool's low confidence score (0.036) confirms that the windows are not clearly present or identifiable in this specific view, effectively meaning they are undetected/non-visible for the purpose of this question.

Answer: 2


Explanation: Although the image clearly shows the handlebar stem, the question specifically asks about the 'handlebar' as detected by an object detection tool. The tool provides a confidence score of approximately 0.0027, which is far below the 0.1 threshold for a valid detection. This low score typically indicates that the model was not confident in identifying the specific object (the handlebars themselves, distinct from the stem) or that the object is absent. Therefore, according to the specific constraints given by the user regarding the tool's output, the handlebar is considered undetected.

Answer: 2


Explanation: Upon visual inspection of the image, the saddle (seat) is clearly missing from the seat post, which is visible but protrudes very low. The object detection tool's confidence of 0.0275 is extremely low, falling well below the 0.1 threshold, which correctly classifies the seat as undetected. This aligns with the visual evidence that the object is absent.

Answer: 2


Explanation: Upon examining the provided image of the green PEdego Element electric bike, there is a focus on the drivetrain area. This includes the chain, rear gear cassette, and a chain cover. However, the pedals, which are attached to the crankset, are not visible in this specific view. They might be obscured by the chain guard or are outside the frame of the photo. The object detection tool's output, with a very low confidence score of 0.0169, confirms that the detection is unreliable and the pedals are effectively not detected or visible.

Answer: 2


Explanation: The image shows a standard disposable coffee cup lid, which typically features a small sip hole. Upon close inspection, a very small, dark, circular opening is visible on the lid. However, compared to the rest of the lid's surface, it is extremely subtle and blends in, making it difficult to distinguish without careful scrutiny. Therefore, while present, it is not 'clearly visible' in a straightforward glance; it is visible but hard to see due to its small size and low contrast with the white lid.

Answer: 1


Explanation: The image shows the back of an iPad. While the word 'iPad' is visible at the bottom, the iconic Apple logo (the bitten apple silhouette) is not present on the back of this device. In many modern iPad models, the Apple logo is not printed on the back casing. The object detection tool's output of 0.0045... with low confidence further supports that the logo is effectively undetected or not present. Therefore, based on both visual inspection and the provided tool confidence (which is well below the 0.1 threshold for detection), the Apple logo is not visible.

Answer: 2


Explanation: The image shows the back of an older model iPod, identifiable by the Apple logo and the text 'iPod' at the bottom. These devices do not have rear cameras. An object detection tool has identified a 'camera' with a confidence score of 0.017, which is far below the 0.1 threshold for a true positive, thus confirming that no camera is actually visible.

Answer: 2


Explanation: An object detection tool analyzed the image and found speaker holes, but with a very low confidence score of approximately 0.019. Since this score is significantly lower than the 0.1 threshold for a reliable detection, it effectively means the speaker holes were not detected or are not visible to the model. This aligns with a visual inspection where no speaker grilles are apparent on the back of the device.

Answer: 2


Explanation: Although the charging port (30-pin connector) is physically visible on the bottom edge of the phone in the image, the provided object detection tool failed to identify it with high confidence, returning a score of approximately 0.009. Since the threshold for detection is defined as 0.1, the tool considers the object to be effectively undetected.

Answer: 2


Explanation: Although the object detection tool returned a confidence score of 0.037 for the home button, which is below the threshold of 0.1 for detection, a visual inspection of the image clearly reveals a prominent circular home button at the bottom center of the phone's front face. Detection tools can sometimes fail on specific features, but human visual evidence takes precedence in this context.

Answer: 0


Explanation: The image displays the bottom edge of an iPhone 5. This specific model is known for having removed the 3.5mm headphone jack, replacing it with a Lightning charging port. The object detection tool's very low confidence (0.0038) further confirms that the object is not present. The bottom edge shows the light port and speaker grilles, but no headphone jack.

Answer: 2


Explanation: Although the earpiece speaker is physically present on the device, the object detection tool provided has a very low confidence score (0.032) for detecting 'speaker holes'. Since the user defines a confidence threshold of 0.1 to mean 'undetected', we must conclude that the tool failed to detect them. Therefore, for the purpose of this question based on the tool's output, they are considered not visible.

Answer: 2
