public interface StereoDisparity<Image extends boofcv.struct.image.ImageGray,Disparity extends boofcv.struct.image.ImageGray>

Given two rectified images compute the corresponding dense disparity image. Input images are assumed to be rectified along the x-axis. Disparity goes from left to right image, thus the x coordinates of pixels in the left and right images have the following relationship x_right = x_left + disparity, and y_right = y_left.. To speed up calculations only a limited range of disparities are considered from minDisparity to maxDisparity. Image borders are not processed and the border size is specified by functions below.

DISPARITY IMAGE FORMAT: Returned disparity image is offset from the true value by minDisparity. This is done to maximize storage efficiency. To get the actual disparity value simply extract the value of a pixel and add minDisparity to it. Invalid pixels are indicated by having a value greater than (maxDisparity - minDisparity).
