Accurate Early Detection of DiscontinuitiesJames

چکیده
Displacement must be determined in both stereo and optical ow computation. Correlation or Sum of Differences can produce robust displacement estimates. To improve its performance near occlusions and dis-occlusions, we construct new estimators from a priori analysis. We introduce smoothly decaying summation functions into Sum of Diierences operators to improve their reliability. Moreover, we show how occlusions can be simply detected by comparing the outputs of support windows of diiering size and orientation. We report the behavior of the system on real and synthetic images.
