Similarity measures for image matching despite occlusions in stereo vision

Sylvie Chambon, Alain Crouzil
2011 Pattern Recognition  
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  ...  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.  ...  The main measures are the Sum of Absolute Differences, SAD (L 1 norm), the Sum of Squared Differences, SSD (L 2 norm), and the Kolmogorov-Smirnov distance, D ∞ (L ∞ norm).  ...

Their outside perspective provided me with numerous suggestions to improve the written presentation of my work.  ...  In this context, I'm especially grateful to Henning Bitsch, who continued to improve upon his already excellent work out of personal interest long after he received his university degree.  ...  measures stemming from information-theory such as the Kullback-Leibler or Jenson-Shannon divergences and finally nonparametric test statistics like χ 2 (Chi Square) and the Kolmogorov-Smirnov distance  ...
