public abstract class DescribePointPixelRegion<T extends boofcv.struct.image.ImageGray,D extends TupleDesc>
extends DescribePointRectangleRegion<T>

Describes a rectangular region using its raw pixel intensities. Score between two regions of this type is typically computed using Sum of Absolute Differences (SAD). If the descriptor goes outside of the image bounds those pixels will be set to zero in the descriptor.
