摘要
确定肤色对彩色图片中的人脸检测很重要 ,在这篇论文中 ,作者首先讨论了用 3种颜色空间表示的肤色子空间 :YCbCr,HSV和统一的颜色空间。然后作者给出了算法 ,判断在 3种肤色子空间下 ,一个象素是否为皮肤象素 ;并且提出了一种新的方法来找出候选面部区域。最后 ,作者比较了 3种肤色子空间的性能。
Detect skin color region is important for face detection in color images. In this paper, the author discusses three skin color subspace in different color spaces: YC bC r, HSV and Unite Color Spaces. Then gives an algorithm to judge whether a pixel in color image is a skin pixel, in three color subspaces. And a novel scheme for candidate face region detection is given. Finally, the author compares the performance of the three color models.
