Computer Vision: Classification, Detection, Segmentation
Vision tasks form a ladder of increasing spatial precision: classification labels the whole image, detection draws bounding boxes around objects, semantic segmentation labels every pixel by class, and instance segmentation separates individual objects pixel by pixel. Each has its own output format and metric (top-1 accuracy, mAP at IoU thresholds), and CNNs versus vision transformers trade off differently across them.
