基于Voronoi图的自动白平衡算法
Automatic White Balance Algorithm Based on Voronoi Figure
摘要
Abstract
In processing of the digital camera image, automatic white balance is used for partial color revised under different color temperature. In many cases, ordinary algorithms for auto white balance can not return true color images exactly. Aiming at this problem, this paper introduces an automatic white balance algorithm based on Voronoi figure. It uses Voronoi figure to statistics white point number, estimates immediate environment color temperature value, does gain calculation, and corrects images according to the standard images. Experimental results show that this algorithm can improve the image quality in different environment.关键词
