Semantic Segmentation
Computer Vision
A form of image analysis that assigns a category label to every pixel in an image, grouping all pixels of the same type together. Unlike instance segmentation, it doesn't distinguish between individual objects of the same class — two cars in the same frame would be labeled identically rather than separately. Semantic segmentation is used in applications where understanding what fills each region of an image matters more than counting or tracking individual objects.
