摘要：

This paper proposes a new way to clear up the fog which softly combines dark channel with color attenuation, namely DCP and CAP. The main task is to solve the bad performance in the sky and white bright regions based on the DCP and the problem of incomplete defogging near the object of the foreground based on the CAP. A quad-tree search method is applied to look for the atmospheric light A. We can choose the pixel average of the last image block as A to solve the problem of excessive saturation. The guided filter is applied to adjust the final medium transmission. By experiments, the results can prove that the proposed method is effective.
