Hybrid Skin Detection Algorithm for Face localization in facial Expression Recognition

An Intelligent Biometrics systems aims at localizing and detecting human faces from supplied images so that further recognition of persons and their facial expression recognition will be easy. Based on facial expression; it is easy to detect intension of person if they are involved in some terror activities or not. This paper presents an automatic, fast and efficient detection of face from an image so that the detected face can be used for facial expression recognition. Images obtained from Sony make digital camera (resolution 7.1 Mega pixel)/Emotion database are considered for our work. Method used includes combination of skin detection algorithms such as modified RGB, YCbCr and HSV and gives better results. Experimental result shows that the algorithm is good to detect and localize human face in an image with better accuracy.
