| Abstract: | We present a novel method for learning overcomplete dictionaries that are optimized for stereo image representation. Our learning algorithm optimizes the construction of dictionaries for both efficient image approximation and epipolar matching between pairs of images. The multi-view geometry constraint is included in the probabilistic modeling that permits to maximize the likelihood that natural stereo images are efficiently represented with the selected dictionaries. Experimental results of dictionary learning for stereo omnidirectional images show that the multi-view constraints significantly influence the construction of the dictionary, which leads to atoms with high anisotropic characteristics. |
