The paper presented here is an attempt to use a very basic and low cost edge detection algorithm for face recognition. The applications instigated from such an attempt will result in inexpensive face detection and face recognition system that can automatically perform matching of an image. The automatic recognition of human faces presents a momentous challenge to the pattern recognition research community. Human faces exhibit similar structure with minor differences from individual to individual. In addition, variations in the lighting conditions, facial expressions, poses and angles further set hurdles to the face recognition task. This paper proposes a novel approach, "Faces can be recognized using canny edge detection algorithm". A face pre-filtering technique is proposed to speed up the searching process. The proposed system provides a sound platform to perform face recognition and display the result on LCD. This paper presents a preliminary approach to perform matching of any image and display the result on LCD using Canny edge detection algorithm, image processing tools and PIC microcontroller.
