Remarks

For Beginners: YOLOv8-Seg extends YOLOv8 detection with a segmentation head. It uses prototype masks and per-instance coefficients for efficient mask prediction. This is much faster than Mask R-CNN while maintaining good quality.

Key features: - Single-stage detection + segmentation - Prototype-based mask assembly - Shared backbone with detection head - Real-time performance
