Choosing Matches

The following buttons perform match selection. Only one of them can be used as they result in chosen matches is selected and all other potential matches are rejected. Each uses the cost options defined above to determine which currently stored support value to use as the basis of selection.

• wta. Use winner take all strategy (WTA) along rasters to select matches. Most strongly supported matches are fist chosen. Inconsistent matches are then eliminated. This continues until all matches are selected.

  Options;

  WTA     unique : Enforce uniqueness with respect to left and right
                   images. (Inconsistent matches are those which
                   violate uniqueness).
          order  : Enforce ordering constraint between left and right
                   images. (Inconsistent matches are those which
                   violate order).
  

• DP order. Use dynamic programming to enforce the ordering constraint along the epi-polar raster.
• string tot. Select matches on the basis of globally matched edge strings, with respect to each left hand edge string. Each partial edge string in the left image obtains a unique match subject to the condition that the most strongly supported match strings are selected first. This does not inforce order or uniqueness.
