Legacy ImageMagick Discussions Archive

Greetings,

I found IM's information page on discrete Laplace operators ( http://www.imagemagick.org/Usage/convolve/#laplacian ) to be very helpful to some scientific computing I am doing. While I can find some academic discussions of discrete Laplacians, I have found only a couple of references that mention kernels at all, and none with the informative descriptions of the effects of the various kernels that you have on that page.

Can anyone recommend a book or other publication that goes into similar detail about the properties of the various discrete Laplacian kernels that might make a good academic reference? Thanks very much!

See the book by William Pratt, "Digital Image Processing", Wiley Publications, 1978, p482 and 484

P.S. You may be interested in my derivations at http://www.fmwconcepts.com/imagemagick/ ... tering.pdf

I would suspect the book by Gonzales and Woods, would also have such information. See http://www.amazon.com/Digital-Image-Pro ... 0201180758

Dear Fred,

Your paper is a great help and I'll cite it as a source if that's all right. I will also investigate the books you mentioned.

Thanks,
Eric

No need to cite my tutorial if the books provide what you need.
