Fast Image Dehazing Method Based on Dark Channel Prior
Xiao Zhongji · Jilin Normal University Journal · 2014
The principle of dark channel prior to fog algorithm was discussed in the paper,and the soft matting smooth and refined transmittance was achieved using a quick and efficient Butterworth low-pass filter instead of the complex method according to the shortcoming of time complexity of the algorithm. For the white edge image existing at the junction of the phenomenon in depth of dark colors,the method of seeking the maximum area was used,and an adaptive algorithm for solving global atmospheric light was also given in the paper. Experimental results showed that the improved algorithm in the dark passage to fog the image not only obtained satisfactory results but also greatly increased the speed of the image to fog algorithms to achieve the real-time applications requirements of engineering.
