Stereo image segmentation usually incorporates depth cues to achieve high quality. However, previous methods that pointwise propagate information within stereo pairs could suffer from a poorly estimated depth map. In this paper, we introduce a novel graphical model where a greater amount of reliable messages can be conveyed during two-view joint segmentation. This model leads to a strongly coupled stereo pair, thus improving robustness, accuracy and consistency of stereo segmentation. Additionally, we augment a depth map to a novel correspondence matrix which is suitable for the proposed stereo segmentation model. Our experiments on a public stereo dataset show that the proposed correspondence method and stereo model outperforms state-of-the-art stereo segmentation algorithms.
