摘要: 为了解决不同光照条件下的肤色分割问题,提出了一种新颖并且行之有效的解决方法。该方法先应用颜色恒常性算法对图像光照进行估计,根据光照估计的结果,在YCbCr颜色空间采用不同分布的高斯肤色模型,并利用动态阈值对图像进行分割。试验结果证明了算法的可行性和优越性。

Abstract: In order to extract skin color under varying illumination,this paper introduces a novel and effective method.Firstly color constancy algorithm is used to estimate the illumination of the image,then different Gauss skin models are built according to different illuminations,and automatic-thresholding technique is used for skin-color segmentation.The experiment results show that it is feasible and rather successful.

Key words: color constancy, Gauss model, skin segmentation
