Unsupervised Segmentation This pytorch code generates segmentation labels of an input image. Methods that learn the segmentation masks entirely from data with no supervision can be categorized as follows: (1) GAN based methods [8,4] that extract and redraw the main object in the image for object segmentation. We have successfully integrated this deep learning scheme into a state-of-the-art multi-atlases based segmentation framework by replacing the previous hand-crafted image features by the hierarchical feature representations inferred from the two-layer ISA network.
