Weakly supervised image segmentation is a challenging problem in computer vision field. In this paper, we present a new weakly supervised image segmentation algorithm by learning the distribution of spatially structured super pixel sets from image-level labels. Specifically, we first extract graph lets from each image where a graph let is a small-sized graph consisting of super pixels as its nodes and it encapsulates the spatial structure of those super pixels. Then, a manifold embedding algorithm is proposed to transform graph lets of different sizes into equal-length feature vectors. Thereafter, we use GMM to learn the distribution of the post-embedding graph lets. Finally, we propose a novel image segmentation algorithm, called graph let cut, that leverages the learned graph let distribution in measuring the homogeneity of a set of spatially structured super pixels. Experimental results show that the proposed approach outperforms state-of-the-art weakly supervised image segmentation methods, and its performance is comparable to those of the fully supervised segmentation models.
