Dear friend! My code is only a prototype of FLD-based face recognition systems. In fact, this code implements the core algorithm for the system. So, you shouldn't expect it to work well on all datasets. Instead, you can customize it according to your needs and used facial images.

Tsai, I forgot to mention that Sb should be multiplied by the number of pcitures per class (in this case 2), you are right on that too. Refer to section 2.4 of the following paper to note the error: http://www.face-rec.org/algorithms/LDA/belhumeur96eigenfaces.pdf

If you guys would like to look at another sample Matlab code for fisher faces, look at:

Tsai there is a mistake indeed; the order of the eigenvectors is backwars, and you are using the eigenvectors with less relevance.

In line 43 of FisherfaceCore.m, you have to substitute line 43:

"for i = 1 : P-Class_number"

for

"for i = P:-1:Class_number+1"

This will solve the problem. I tested with all the faces in the sample set, and it was 90% accurate.

Everything has been working perfectly, thanks for an excellent and well commented code Amir!

excellent

nice work.... very thanks.. when i am trying to import another photos but it shows
??? Error using ==> horzcat
CAT arguments dimensions are not consistent.

Error in ==> CreateDatabase at 47
    T = [T temp]; % 'T' grows after each turn

Error in ==> example at 26
T = CreateDatabase(TrainDatabasePath); how to clear this errors... any one help me to clear this error..........
