Studies on face contour extraction from approximate skin color backgrounds
类肤色背景中提取人脸轮廓的方法研究

A new face contour extraction method was proposed by useing skin color and multiple information fusion. The method computed skin probability image based on TSL color space, then selected seed point, finally used multiple information to carry out region growing, extracted face contour. The method employed image pyramid process to avoid heavy computing burdens caused by region growth. Experiment results indicated that the proposed algorithm can extract face contour from approximate skin color backgrounds efficiently and accurately, and bears noise endurance and application adaptability.
