Adaptive Defogging of a Single Image
Bo Yao, Lei Huang, Changping Liu · 2009
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.
