**Image Segmentation** is a foundational deep learning task in computer vision where algorithms classify every individual pixel in a digital photograph.
### Types of Segmentation 1. **Semantic Segmentation**: Groups all pixels of a class (e.g. "person") under a single label. 2. **Instance Segmentation**: Differentiates between individual instances of an object (e.g. Person 1 vs Person 2). 3. **Dichotomous Segmentation**: Separates primary salient foreground objects from background elements for instant cutout extraction.
