摘要
Abstract
This paper proposes a method of head-shoulder segmentation and human facial feature allocation for videotelephone application. 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.关键词
