(English Abstract)
This paper describes a new face detection method that is a pre-processing algorithm for on-line face recognition.
To complement the weakness of using only edge or color features from previous face detection method, we propose the two types of face detection method. The one is a combined method with edge and color features and the other is a center area color sampling method. To prevent connecting the people´s face area and the background area, which have same colors, we propose a new adaptive edge detection algorithm firstly. The adaptive edge detection algorithm is robust to illumination variance so that it extracts lots of edges and breakouts edges steadily in border between background and face areas.
Because of strong edge detection, face area appears one or multi regions. We can merge these isolated regions using color information and get the final face area as a MBR (Minimum Bounding Rectangle) form. If the size of final face area is under or upper threshold, color sampling method in center area from input image is used to detect new face area.
To evaluate the proposed method, we have experimented with 2,100 face images. A high face detection rate of 96.3% has been obtained.
