Quantitative evaluation of matching methods and validity measures for stereo vision
 
Multimedia extension #5: Application of constraints to remove invalid matches
 
All disparity maps are computed using the rank transform with a 5 x 5 window. In order for a pixel to be valid it must pass:
 
• pass the left-right consistency check
• the local anomoly test
• local texture test
• match score test
• ambiguity score test
