摘　　要：为了有效地检测唇部,在综合考虑唇色和肤色3个颜色分量的差异后,对红色排除法判别式进行改进,提出了嘴唇BR加权G色对比法(WBRGC)。该方法利用G,B分量和G,R分量分布差异加权来区分肤色和唇色,最优权重通过实验确定。实验表明,WBRGC的检测性能与红色排除法相比有明显的提高。It presents a new method called WBRGC（weighing blue color and red color contrast green color）, which improves the expression of the red exclusion. WBRGC discriminates skincolor and lip - color by taking advantage of the weighted average between the distribution difference of R, G component and G, R component. This approach acquires the best weight in conducting experiment. The experiment results show that the detecting performance is better than red exclusion method.
