# Instance Segmentation

Test instance segmentation models. Detect imbalance, drift, and labeling quality issues.

Instance segmentation takes semantic segmentation a step further by not only labeling each pixel with a particular class but also distinguishing between different instances of the same class. In essence, instance segmentation provides a detailed understanding of the objects present in an image, delineating boundaries and identifying individual objects separately. This level of granularity is important in various applications.
