    Semantic Segmentation is an image analysis task in which we classify each pixel in the image into a class. This is similar to what us humans do all the time by default. Whenever we are looking at something, then we try to “segment” what portion of the image belongs to which class/label/category.

Image semantic segmentation is a task of predicting a category label to each pixel in the image from C categories. A segmentation network takes an RGB image Iof size W × H×3as the input, then it computes a feature map Fof size W′ ×H′ ×N, where N is the number of channels.
