jit.robcross Robert's Cross edge detection The jit.robcross object implements the Robert's Cross method of edge detection. 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.	from the library : Jitter Format : External Environment : jitter commercial Max 4.x http://www.cycling74.com
