摘要
本文提出了一种基于先验知识的自动白平衡方法。在对包含人脸的数字图像进行白平衡处理时，依据人脸肤色的色差分量集中在一个比较小的区间这一实验结果，不需要白色参照物，自动完成白平衡。模拟结果表明本文提出的白平衡算法取得了较好的效果。
A new algorithm for automatic white balance is presented. Without any reference object, white balance can be performed automatically on a digital image which contains a human face, based on the observation that the value of UV components in a human face are concentrated in a small area. Simulation results show its good performance.
