If this option is enabled, a right-to-left disparity map will be computed independently from the normal left-to-right disparity map. It is used to validate the disparities in the left-to-right map. The shadowing filter will only accept matches which agree in both views (up to the shadowing threshold). This can help to remove mismatched values, but small details will only be reconstructed if they were successfully matched in both views.

Note that computing two independent perspectives will take twice the amount of computation time. For a less costly variant of this parameter, you can enable CoupledPropagation.


The right-side disparity map is currently kept internal and not available through the API.



Specifies whether to validate the disparity map against an independently computed right view.
