几种常用的肤色检测颜色空间

Several Commonly Used Color Spaces for Skin Color Detection

本文主要介绍了一种常用的肤色检测方法即肤色区域边界固定法,同时介绍了利用该方法进行肤色检测的几种常用的肤色检测颜色空间如RGB、YCbCr以及HSV颜色空间,并在这几个颜色空间中对在Internet上获取的200个光照均匀的肤色块进行肤色检测,统计出在每个颜色空间中肤色检测的正确率并对实验结果做出分析。最终的实验结果表明,在所取图片的光照比较均匀的条件下,HSV颜色空间的肤色检测效果最佳,YCbCr颜色空间次之,RGB颜色空间最差。

This paper mainly describes a skin color detection method called fixation of skin color region boundary. At the same time,the paper introduces several color spaces such as RGB,YCbCr and HSV col-or spaces which are commonly used in this method. Then, do skin color detection in these three color spaces on 200 skin color regions whose illumination is uniform ( all the 200 skin color regions are down-loaded from internet) . Count the accuracy of skin color detection in every color space and analyze the re-sult of the experiment. The final result of the experiment shows that when the illumination is relatively uni-form,the highest and lowest accuracy of skin color detection are respectively in HSV color space and RGB color space,YCbCr color space is in between.
