Image segmentation is a computer vision task that divides an image into multiple constituent regions by utilizing the correlation between pixels. This approach does not require pixel-level label information during the training phase. Consequently, it cannot guarantee that the resulting segmented regions will map to specific, predefined semantic categories during prediction. For example, it might divide an image of a dog into a dark region covering the face and a light region covering the body, rather than identifying the entire object as a single semantic entity.
