What is Instance Segmentation?

Instance segmentation is a powerful annotation technique that not only identifies each object in an image at the pixel level (like semantic segmentation) but also distinguishes between multiple instances of the same class. For example, instead of labeling all cars as one class, each car is uniquely segmented. This enables AI models to count, separate, and analyze individual objects with extreme accuracy.
