We are asked to do a facial expression recognition system that uses back propagation neural network. I am not really familiar with neural networks and how could i use matlab to implement facial expression recognition.

Does anyone have a source code for back propagation?? and also, how would i be able to apply it on facial expression recognition.?

Please, if you know something, just send a message or reply to this thread.

Thanks!!

see the neural network toolbox documentation.

hope this helps.
