Make a face recognition algorithm using edge detection

Is it possible to make a face recognition algorithm or a face detection algorithm by using edge detection methods??? And if is it possible...how can i make it and which is the best method to choose???

See functions in the Computer Vision System Toolbox. No need to write it from scratch since there are built in functions for this.

yes...but how can i detect a face in an image using an edge detection method or to recognize it for identify a person???

[Image Analyst]

The toolbox uses the Viola Jones method which uses Haar features, which are a type of edge detector. https://en.wikipedia.org/wiki/Viola%E2%80%93Jones_object_detection_framework

thank you a lot for you reply sir...i was wondering if i could use an edge detection method like: sobel, prewitt, canny,e.t.c. to detect the face or recognize it?? is that possible??

Perhaps, but don't you think Viola and Jones thought of those edge detectors and there was a reason why they chose the Haar detector?
