Facial Expression Recognition Based on Edge Detection

Abstract

Relational Over the last two decades, the advances in computer vision and pattern recognition power have opened the door to new opportunity of automatic facial expression recognition system[1]. This paper use Canny edge detection method for facial expression recognition. Image color space transformation in the first place and then to identify and locate human face .Next pick up the edge of eyes and mouth's features extraction. Last we judge the facial expressions after compared with the expressions we known in the database. This proposed approach provides full automatic solution of human expressions as well as overcoming facial expressions variation and intensity problems.
