- I've heard of, and seen, the effect known as a "first dirivitive" (sp). Can
- anyone fill me in on how this operation is done? Is it a simple convolve
- matrix?
-
- The way I understand it, the difference between adjacent pixels is taken as
- the color for the pixel in question, but, whenever I attempt this operation,
- the result is less than desireable.
-
- Any help would be greatly appreciated? (ie. reference, source, description)
