Support-Weight based on Grouping


 1) Gestalt grouping in stereopsis 

   - Figure-ground discrimination

   - Marr’s stages of visual processing


 2) Support-weight based on grouping

   - Support-weight is in proportion to the strength of grouping.

   - Main gestalt grouping laws: similarity, proximity

Dissimilarity Computation (Matching cost)

 Using the support-weights in both support windows

   - Symmetric measure

   - Suppressing the effect of outliers
