Effective haze removal under mixed domain and retract neighborhood

The quality of images would exhibit degraded visibility during inclement weather conditions. We proposed a novel method for estimating an optimal transmission map and recovering the real scene. Under HSI color model, saturation layer and intensity layer are mixed together for obtaining the rough transmission. To avoid halos and artifacts, proposed approach employs edge preserving constraint of shrinkage neighborhood on the color line model, which can maintain maximum smoothness and sharp edges in the refined transmission map. A comparative experiment with a few previous methods shows improvement visual results.
