Subject: [linux-graphics-dev] Simple Reusable Library for applying a
	convolution matrix to an image
Message-ID: <4af8d6ff0802190850x2b954420rd215b20bf362aaa5@mail.gmail.com>

Hi,

I am looking for some example code to apply a 3x3 or eventually 5x5
convolution matrix to an RGB image. I'd prefer to use a library, like
fftw.

Are you aware of a some example code, or anything helpful?

I am working with video, so interesting approaches to doing this
stuff, fast, would be nice as well. :-)

Cheers
-Richard

GraphicsMagick - http://www.graphicsmagick.org (a spinoff of
ImageMagick focused on performance and reliability) has lots of
algorithms for image and video manipulation.
