which feature extraction use for face recognition ???

I tried PCA a good method it can reduce the number of pixel to the number of input images but if i have a large data base its not very relevant ,in my case i have 3016*38416 input matrix where 3016 is the number of images and 38416 =196*196 the dimension of each image .when i used the pca the input matrix was reduced to 3016*3016 .

For algorithm questions like this, first check the literature to find an algorithm. Then code it up in MATLAB. Then you can ask us questions on MATLAB programming if you need to.
