Zhong Hai Li, Xing Yuan Kou, Hong Yan Cao, Xiang Man · Applied Mechanics and Materials · 2014
In this paper, on the basis of the classical Retinex enhancement algorithm, we propose a MSR (Multi-Scale Retinex) algorithm based on HSI color space for foggy images enhancement. This algorithm can self-adaptively choose the Scale of the filter function, and it can automatically merge the enhancement effect of the multi-scales. The algorithm can highlight the detail characteristics of target while maintaining the background smoothly. In order to improve the brightness and contrast of the image, we use the Weber's law and the characteristics of human visual system to select the scale parameters, which can better realized the foggy images enhancement.
