Utilizing the characteristic of multi resolution processing of human eyes, analyzing the edge information of only a single frame in different frequency bands, this method can automatically perform head shoulder segmentation and locate the facial feature regions (eyes, mouth, etc.) with rather high precision, simple and fast computation. Therefore, this method makes the 3 D model automatic adaptation and 3 D motion estimation possible. However, this method may fail while processing practical images with a complex background. Then it is preferable to use some pre known information and multi frame joint processing.
