the class FactoryStereoDisparity method regionSparseWta.

/**
 * WTA algorithms that computes disparity on a sparse per-pixel basis as requested..
 *
 * @param minDisparity Minimum disparity that it will check. Must be ≥ 0 and < maxDisparity
 * @param maxDisparity Maximum disparity that it will calculate. Must be > 0
 * @param regionRadiusX Radius of the rectangular region along x-axis.
 * @param regionRadiusY Radius of the rectangular region along y-axis.
 * @param maxPerPixelError Maximum allowed error in a region per pixel.  Set to < 0 to disable.
 * @param texture Tolerance for how similar optimal region is to other region.  Closer to zero is more tolerant.
 *                Try 0.1
 * @param subpixelInterpolation true to turn on sub-pixel interpolation
 * @param imageType Type of input image.
 * @param <T> Image type
 * @return Sparse disparity algorithm
