What's New
Patch release fixing Pillow conversion, dataset exports, and line-crossing tracking logic.
Improvements
- Refactored `pillow_to_cv2` to correctly handle all Pillow image modes.
- Dataset split methods now raise `ValueError` for out-of-range ratios.
Bug Fixes
- `pillow_to_cv2` now correctly converts 1-bit masks, 16-bit depth maps, and CMYK JPEGs.
- `LineZone.trigger` no longer allows unconfirmed tracks to inflate crossing counts.
- `DetectionDataset` export methods now correctly handle mixed polygon/box datasets.
- `DetectionsSmoother` no longer crashes on mismatched tracked object metadata.
- `MeanAverageRecall` now correctly scores mAR@K from each image's top K predictions.
Upgrade Notes
No breaking API changes, but dataset split methods now raise `ValueError` for invalid ratios. Ensure your code handles potential errors when splitting datasets.
