| 摘 要： | 白平衡是照片处理过程中决定性的一步,它根据不同的光源消除色偏,确保原始的图像能够再现。现有白平衡算法中最为经典有效的有灰色世界法和RGB最大值法,它们都是在单光源的前提下进行白平衡处理的,可是很多情况下照片是在双光源或者混合光源的情况下拍摄的。因此,本文在研究单光源白平衡算法的基础上,直接对RAW格式的图片进行白平衡处理,提出了基于RAW格式的图像双光源白平衡算法。实验表明我们的算法能获得满意的处理效果。

| Abstract: | White balance is a key step in the photographic pipeline.It ensures the proper rendition of images by eliminating color casts due to differing illuminants.In the existing white balance algorithm,the most classic and effective methods are the Grey-World and the max-RGB which both do white balance under single lighting.However,in most cases,photos are all taken under two lighting or mixed lighting.Based on the study of white balance under single lighting algorithm,this paper propose a white balance algorithm ... |
