Looking for a solid implementation of despeckling and deskewing

Hello:

I am searching for implementations (with source code) of despeckling and deskewing.

Preferably based on the OpenCV library. My targets are TIFF files.

If there is some algorithm or code somewhere, I am willing to port it and/or implemented myself.

Any tips and pointers are much appreciated.

You might want to look at ImageMagick. Among the very many Options is -despeckle.

See: http://www.imagemagick.org/script/index.php, look at Architecture and Options first to get an idea. Cruise the code. You know, the usual drill.

I use it less and less now that I've CS3 over OS-X with scripting. Enjoy.

For despeckling, do a search for impulse filter, or median filter. For deskewing, check out Alvy Ray Smith and Ed Catmull on two-pass convolutions, specifically rotation which is implementd as a pair of skew operations.
