A Novel Binary-valued Hopfield Network Based Iterative Approach to Stereo Matching
Traditional neural network algorithms for stereo matching often suffer the poor performance and slow or premature convergence. In order to avoid these problems, a novel Hopfield network based iterative stereo matching approach is proposed. Firstly, the optimal search problem of disparity map is transformed to an iterative convergence process of binary-valued neural network, whose maximal number of neurons is the size of image. Secondly, the disparity prelabeling based on local matching method is used to initialize the weights of neural network. Moreover,according to the implicit assumption in local matching algorithms, two evaluation criteria are proposed to determine the disparity range of each pixel, which can reduce the number of active neurons in each iteration.Experiments indicate this approach is much better than traditional algorithms in performance and convergence speed.
