**Annotation format:** YOLOv8
**Total images:** 1,512
## Dataset Description
This dataset contains annotations of stains found on historical documents for the purpose of object detection model training. It includes five stain categories: **foxing and feces**.
The dataset was created as part of the **HIPSI research project** (APVV-23-0250), in collaboration with the **Institute of Molecular Biology of the Slovak Academy of Sciences** and the **Academy of Fine Arts and Design in Bratislava (VŠVU)**.
Images were partially annotated and preprocessed using **Roboflow**, and exported in **YOLOv8 format**.
## Image Preprocessing
Each image was processed as follows:
- Auto-orientation correction (EXIF orientation removed)
- Resized to **1280x1280** (stretched)
## Augmentation (3 variants per image)
The following augmentations were applied:
- **50% probability of horizontal flip**
- **Random 90° rotation**: none / clockwise / counterclockwise / upside-down (equal chance)
- **Random crop**: 0–20% of the image
- **Random rotation**: between -15° and +15°
- **Random brightness adjustment**: ±15%
- **Random exposure adjustment**: ±10%
## License
This dataset is intended for **research and non-commercial use only**.

The dataset includes 1512 images.
Stains-KqL0 are annotated in YOLOv8 format.
The following pre-processing was applied to each image:
* Auto-orientation of pixel data (with EXIF-orientation stripping)
* Resize to 1280x1280 (Stretch)
The following augmentation was applied to create 3 versions of each source image:
* 50% probability of horizontal flip
* Equal probability of one of the following 90-degree rotations: none, clockwise, counter-clockwise, upside-down
* Randomly crop between 0 and 20 percent of the image
* Random rotation of between -15 and +15 degrees
* Random brigthness adjustment of between -15 and +15 percent
* Random exposure adjustment of between -10 and +10 percent
