A New Fog Removing Method Based on the Degradation Model

Aiming at the degeneration phenomenon of images taken in mist, according to features of the drop quality image, using contrast attenuation of atmosphere scatter model and the mist image has the relation of index with image depth, this paper puts forward a kind of algorithm which estimates scene optical depth from several drop quality images based on degradation model, and then the method is applied to drop quality image fog removing. The experimental results show that the method can effectively improve the fog degeneration phenomenon and improve image clarity, significantly improving drop quality image visual effect.
