The latter is more challenging than the former. We conducted extensive experiments to evaluate the proposed method on a famous publicly available dataset, and the experimental results demonstrate the effectiveness of the proposed method. Unsupervised clustering, on the Med. 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. Xu, Z., Lee, C., Heinrich, M., et al. IEEE Trans. 2020LKSFG05D). We use spatial regularisation on superpixels to make segmented regions more compact. Such methods are limited to only instances with two classes, a foreground and a background.
