+# Stanford Cars with SAM3 Segmentation Masks
+A version of the [Stanford Cars](https://ai.stanford.edu/~jkrause/cars/car_dataset.html) dataset
+augmented with per-image segmentation masks generated by SAM3 (Segment Anything Model 3).
+## Dataset Description
+- **Images**: 196 car model classes, original Stanford Cars images
+- **Masks**: Binary segmentation masks from SAM3, stored as grayscale PNG (255 = car, 0 = background)
+- **Bounding boxes**: `[x1, y1, x2, y2]` pixel coordinates of the primary car object
+- **Splits**: `train` (8,144 images), `test` (8,041 images)
+## Schema
+| Column | Type       | Description                                      |
+|--------|------------|--------------------------------------------------|
+| image  | Image      | Original car photograph (JPEG)                   |
+| label  | int        | Class label (0–195, 196 car models)              |
+| split  | string     | `train` or `test`                                |
+| mask   | Image      | Binary segmentation mask (grayscale PNG)         |
+| bbox   | list[int]  | Bounding box `[x1, y1, x2, y2]` in pixels       |
+## Usage
 ```python
 from datasets import load_dataset
+ds = load_dataset("segmentationAPIs/standford_cars_masks")
+sample = ds["train"][0]
+sample["image"]   # PIL Image — original photo
+sample["mask"]    # PIL Image — grayscale mask (255 = car)
+sample["bbox"]    # [x1, y1, x2, y2]
+sample["label"]   # int class label
+```
+## Class Labels
+196 fine-grained car model classes covering major manufacturers (Acura, Aston Martin, Audi, BMW,
+Bentley, Bugatti, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ferrari, FIAT, Ford, GMC, Honda,
+Hyundai, Infiniti, Isuzu, Jaguar, Jeep, Lamborghini, Land Rover, Lincoln, MINI, Maybach, McLaren,
+Mercedes-Benz, Mitsubishi, Nissan, Plymouth, Pontiac, Porsche, Ram, Rolls-Royce, Scion, Spyker,
+Subaru, Suzuki, Tesla, Toyota, Volkswagen, Volvo).
