Similarity measures for image matching despite occlusions in stereo vision

In the context of computer vision, matching can be done with similarity measures. This paper presents the classification of these measures into five families. In addition, eighteen measures based on robust statistics, previously proposed [1] in order to deal with the problem of occlusions, are studied and compared to the state of the art. A new evaluation protocol and new analyses are proposed and the results highlight the most efficient measures, first, near occlusions, the smooth median powered deviation, and second, near discontinuities, a non-parametric transform-based measure, CENSUS.
