Robert's Cross edge detection

jit.robcross

Description

jit.robcross implements the Robert's Cross method of edge detection.

Examples

Discussion

This particular edge detector uses a 2x2 convolution kernel to compute a 2-dimensional spatial gradient of an incoming matrix, brightening features with "high spatial frequency" -- a large amount of change from cell to cell -- and darkening features with less change.
