A novel Retinex algorithm based on IIR low-pass filter is presented
this method can preserve sharp edges in images
so it doesn’t produce halo.And it is combined with a real-coded Genetic Algorithm.Thus images with different characteristic can be enhanced with parameters choosed automatically.Compared to MSR and MSRCR
results on a series of low-light condition and foggy images show the efficiency of the proposal approach in both clarity and color.
