Retinex在夜景影像增强处理中的色彩补偿应用

Application of Retinex in Color Restoration of Image Enhancement to Night Scene Image

很多监控和侦察影像,都是在夜晚无辅助光的条件下所拍摄的,该影像通常非常昏暗,需要做增强处理,Retinex可以对其做增强处理,并表现良好,但需要色彩补偿.对RGB和HSI色彩空间做对比分析,比较了两者之间差别和优缺点,考虑将Retinex算法从RGB转换到HSI色彩域,构建SSRHSI算法,以期在色彩补偿方面得到新的效果.

Many monitoring and reconnaissance images are shot in night without auxiliary light,so those images are usually very dim and need enhancement processing which can be realized by Retinex with a good effect,but Retinex needs the color restoration. Based on the contrastive analysis of the RGB and the HSI color space,the differences,advantages and disadvantages are compared considering the transformation of Retinex algorithm from the RGB to the HSI to construct the SSRHSI algorithm to obtain the new effect on the color restoration.
