Homomorphic Normalization (Scripts) Publisher's description
from Alan Schoen
Homomorphic normalization corrects uneven lighting and enhances textures in an image
Homomorphic normalization corrects uneven lighting and enhances textures in an image. It is often used as a preprocessing step for biometric identification.
I thought that all of the homomorphic normalization functions which were available were not written well, so I wrote my own. I can't vouch for the math because I haven't read the original paper (Gross and Brajovic, 2003). I just adapted the math from the function available here: http://www.csse.uwa.edu.au/~pk/research/matlabfns/
I simplified the logic so that the code should make sense to a reasonably experienced matlab user and I put the main function and all of the supporting functions in one file.
