Stereo Matching Algorithm based on Aligning Genomic Sequence

S. Yu, D. Yan, Y. Dong, H. Tian, Y. Wang and X. Yu    

Abstract: Presently, stereo matching algorithms are almost in purpose of pursuing high matching precision, the whole time spent in algorithms are too long. In this study, we proposed a stereo matching algorithm based on aligning genomic sequence, according to the comparability on the theory of aligning genomic sequences and stereo matching algorithm. Firstly, pixels in each epipolar on stereo image were transformed into the form of genomic sequences and then used calculation method of getting score matrix by comparison of genomic sequence to establish two-dimensional disparity space images. At last, we finally get disparity using searching optimization strategy in aligning genomic sequences to do global optimization. The experimental results show that the whole time of this method is greatly reduced and matching quality is still good.
