face detection and preprocessing
von1000 opened this issue · comments
Right now, I just write the main core PCA program, to test it, I simply use the database such like AT&T and Yale, which means I don't have to clean the data in advance.
But in real life or in my final system, I have to detect face first, then scale them or do some other tricks, before I finally can identify them.
So this is an important function I'll work on.
