| 摘 要： | 在分析Retinex理论及其经典算法的基础上,提出一种新的彩色图像增强算法。该方法在保持增强图像高频成分的同时,很好地保留了图像的部分低频成分,并根据Gray World理论,引入动态参数,提高了图像的动态范围。实验结果表明,用所提算法能有效增强彩色图像。

| Abstract: | A new enhancement algorithm for color images is proposed after an analysis of Retinex theory and its classic algorithm.This image retains some of the low frequency components of the image while enhancing the high-frequency components.Besides,the dynamic parameters,acquired according to the Gray World theory,are introduced to extend the dynamic range.The experimental results demonstrate that the proposed algorithm is efficient in color image enhancement. |
