基于图像偏色检测的自动白平衡算法研究

摘要

In order to overcome the limitations of traditional methods in image color cast detection, a method based on equivalent circle to detect and classify color cast was applied. A new automatic white balance algorithm which is combined gray world and the perfect relfection was presented. Image white balance correction is implemented according to the scale factor, which is determined by different color cast. Meanwhile, Imatest software is used to assess the corrected images. Experimental results show that the proposed algorithm effectively compensates the lfaws of traditional methods and has better effect.%为了克服传统方法在图像偏色检测中的局限性，采用了一种基于等效圆的偏色检测和偏色划分方法。提出了一种结合灰度世界和完美反射的白平衡算法，根据偏色等级决定的尺度因子对图像进行白平衡校正，采用Imatest软件评测校正后图像。实验结果表明，基于图像偏色检测的自动白平衡算法有效弥补了传统方法的不足，取得了较好的处理效果。
