sir, i am doing final year project on face recognition based oned eigen values, we have the same program that is mentioned here, but it fails to detect the images properly, eg it matches my image with another image loade in database, can you suggest me, what should i do t remove this problem?
This algorithm looks like just what I need for a project I'm working on, but I'm having a problem in the step where interp2 executes. Specifically,
returns a vector where the interior elements are all NaN while the first few and last few are what could be reasonable values.
I'm feeding the function a solid binary block that has been converted to double (so all 1's are now 127 and all 0's are still 0), could this be a problem in that the gradient is very sudden?
