### Homography

Posted:

**Fri Apr 03, 2009 7:49 am**Hi,

I'm not sure if this should be in the Image Processing and Computer Vision board, so, sorry if it should be posted somewhere else. Anyways, I was looking through the AForge.Math (1.7) classes and noticed that there isn't too much support with matrices and all that. Does anyone know of some good Math libraries in C# that I can use? I'm looking to map a captured projected image with the computer. (I.e., a camera captures a projected image on the wall or something, and I want to map a section of that captured image to my laptop screen.) Or better yet, if there's already a math library out there that can compute the homography matrix (with known image and screen points as inputs), that would be great!

Thanks!

Andy
