Single Image Defogging Based On Improved Dark Channel Priority
Hua Jiang, Yong jun Xu · 2015
Though the method of dark channel priority has made meaningful results in the process of single image defogging, it has not worked well in the treatment of the gray area in images. The channel image is related to the transmission distribution rate and concentration of fog. This paper proposed an image defogging method based on the Peak Signal to Noise Ratio(PSNR) and rule of the dark channel priority. The experiments show that the detail of result image using this method is more distinct, and the processing efficient of gray area is better comparing with the original method.
