What is semantic segmentation?
Semantic segmentation: Assigning a class label to every pixel, without distinguishing separate objects of the same class. All pixels of any car are simply 'car'. The result is a map the same size as the image, where every pixel carries a class label.
Semantic segmentation: an example
In a street photo, two adjacent cars form one merged 'car' region in the output map.
