Abstract

A strong machine learning system should aim to produce the full range of valid interpreta- tions rather than a single mode in tasks involv- ing inherent ambiguity. This is particularly true for image segmentation, in which there are many sensible ways to partition an image into regions. We formulate a tree-structured probabilistic model, the stochastic segmenta- tion tree, that represents a distribution over segmentations of a given image. We train this model by optimizing a novel objective that quantifies the degree of match between statis- tics of the model and ground truth segmen- tations. Our method allows learning of both the parameters in the tree and the structure itself. We demonstrate on two datasets, in- cluding the challenging Berkeley Segmenta- tion Dataset, that our model is able to success- fully capture the range of ground truths and to produce novel plausible segmentations beyond those found in the data.
