YCbCr色彩空间的彩色图像光线补偿方法研究

摘要

在进行人脸检测过程中，自然光源光照条件和取景设备对图像原本色彩存在干扰影响，这样很难满足人脸识别系统的要求。从图像进行光照补偿处理的方法和效果的研究出发，实验证明：在图像背景相当简单的情况下，采用参考白光线补偿方法可以很好地对色温差图像进行光照补偿处理，消除了光照的影响力，使后续的处理更适合进行人脸识别性能。%During face detection process, the original color image is affected by the natural light illumina-tion conditions and viewing equipment interference, it is difficult to meet the requirements of face recogni-tion systems. Researching illumination compensation from the image processing method and effect,when the background of the imageis quite simple, the color temperature can be a good illumination compensation processing by using a reference white light which can eliminate the effects of illumination force and make more suitable for face recognition performancein subsequent processing.
