Abstract:

皮肤颜色是人脸检测、定位、跟踪时的一种十分有效的特征,而且裸露的皮肤区域也是色情图像的最重要特征之一.为了有效地进行图像的皮肤检测,提出了一种新的肤色检测方法.该方法首先通过统计1809502个肤色像素点和1763682个非肤色像素点,并使用贝叶斯规则来建立肤色分类器;然后考虑亮度对肤色的影响,采用Y-Cb和Y-Cr两个子空间的查询表来建立肤色模型.为了联合使用两个查询表,先采用高斯归一化和线性化方法来将阈值范围调整至[0,1];同时对查询表进行中值滤波处理,以除去离散孤立点.实验表明,与其他3种方法相比,该方法不仅有着较低的漏检率(9.814%)和误检率(3.5%),而且对于不同光照条件也有较好的检测效果.
