Gray World彩色均衡方法在肤色检测中的应用

摘要

由于受外界光照环境的影响,采集来的人脸彩色图像经常会发生彩色偏移或者存在不同程度的高光和阴影,这已成为提高基于肤色的人脸检测率的重要障碍.为此,将Gray World彩色均衡方法融入人脸检测算法,对待检测图像进行彩色偏移消除,在相当程度上解决了光源色彩不同所带来的色彩偏移问题,这为基于肤色的人脸高检测率的获得提供了保障.%Because of external lighting circumstance, color offset or highight and shadow may exist in collected colorized face image, and these are obstacle of heightening the rate of face detection based on complexion. So, the Gray World color image equalization technique is introduced to the face detection algorithm, color offset of detecting image is eliminated, and problem of color offset caused by the difference of lamp-house's color is solved to a great extent. The mix of this method is the base of high rate of skin color based face detection.
