Adaptive Defogging of a Single Image

Based on the physical model of fogged images, a new method is proposed to enhance the visibility of a single image adaptively. In order to restrain the edge halation produced by virtual air light defogging method, the concept of neighboring pixel´s relative depth information is brought up. Input images may have different extent of disturbance of fog or haze, and they need different strength of defogging adaptively. Hence, we propose a method to calculate the deserved defogging ratio with valid edge intensity. Experimental results have proven the validity and robustness of our proposal.
