| 摘要: |
| 肤色特征在MPEG4、基于内容的图像检索、虚拟现实等领域有着广泛的应用.目前肤色聚类的方法有很多,结果各异,但都没有涉及颜色现象的本质.探讨了人体肤色的基本问题:影响肤色聚类的颜色空间、光源颜色对聚类的影响以及颜色恒常性.提出了用于肤色聚类的新的颜色空间,给出了光源变化和图像数据之间的关系,证明了图像中高光和阴影只影响肤色的饱和度.在此基础上,还给出了人体肤色的聚类结果以及肤色特征在复杂环境中的人脸检测和手势识别中的应用. |

| Abstract: |
| The features of skin color are wide used in the areas of MPEG4, content based image retrieve and virtual reality. Presently, there are plenty of the methods of the skin color clustering and of the varieties of the clustering results. Some elementary problems of the features of skin color, such as the effect of hight source, of color constancy and of color space in which the skin color clustering is performed, are investigated in this paper. A new color space is constructed for the skin color clustering and correlation between the mage data and the color of iluminants is introduced. It is proved that high lights and shading only changes the saturation of the skin color. In this framework, both the results of the skin clustering and their applications in the facial detection and hand gesture recognition in complex background are presented. |
