An Improved MSR Algorithm Based on Wavelet Domain Information Fusion
基于小波域信息融合的MSR改进算法

A novel multi-scale Retinex method is proposed to improve traditional Multi-scale Retinex in this paper, mainly aiming to solve the problem of not being able to maintain the details and the color fidelity effectively, by adopting information fusion strategy based on wavelet transform domain to replace the linear weighted average. At first, the basic strategy of image fusion is taking four wavelet decomposition, then the high-frequency take absolute maximum to enhance the details and the low-frequency adopt the strategy which based on local variance to modify color. The subjective and objective evaluation show that this MSR algorithm is better than the traditional MSR method in details and color fidelity in fog image enhancement.
