Abstract :
The main contributions of this research are: (1) the derivation of the probability density function (pdf) of disparity changes in stereo matching based on the pdf of depth changes in the world and on the parameters of the stereo image formation process, (2) the definition of a match support equation based on the derived pdf, and (3) the incorporation of the support equation into a relaxation matching algorithm. The derived pdf and support equation are applicable to many existing stereo algorithms
