// \brief Routines to calculate disparity based on regions rather than pixels.
//
// The routine takes a form of region segmentation as input.
// The segmentation can be vtol_intensity_faces or vdgl_digital_regions.
// A disparity map for the image is also taken as input.
// The algorithm takes the average of the disparity in each region and
// assigns it to each pixel in the region.
