Face identification with opencv

Question

I'm using the libraries OpenCV for image processing in C + + and this is my question: can you think possible to do a facial recognition (saying the name of a person based on a database of photos) by comparing the frame of videocamera with images in a database using the technique of image histograms comparison? (Note that i compare only the facial region of an image using an example included in the opecv libraries).

I'm asking this because i've just tried to do a program like above but i have a lot of problem (often i detect the wrong person)

Answer 1

You might want to start with compiling the Face Detection using OpenCV example. As others have pointed out, general facial recognition isn't exactly an easy problem to solve. EigenFaces is one common technique for face recognition that is fairly easy to understand and implement.

As others have stated, it's a hard problem, but this gives you a place to start.
