Abstract : In this work, a convex and robust formulation of the unsupervised co-segmentation problem is introduced for pair of images. The proposed model relies on the optimal transport theory to asset the statistical similarity of the segmented regions’ features (color histograms in this work). The optimal transport cost is approximated by Sinkhorn distance to reduce the optimization complexity. A primal-dual algorithm is used to solve the problem efficiently, without making use of sub-iterative routines.
