hi
thanks for the reply
As I mentioned i am a newbie in this area and have implemented a very
basic face rec sys based on the eigenfaces(PCA) method.For testing
out,i need to use images with identical background pixels.I mean
anything beyond the face contours ( i don't know if that is the right
word)should be identical for all images.I have used some pre processed
images available in the net.but i would like to use code to preprocess
the image before testing it with the system.I know the maths involved
is quite complex and may be beyond me..is why looking for an open
source library for that ..
hope i made it clear
