Restoration technology of the video under snow

The snow in video images affects image quality and blurs key objects in the video image. It affects the ability of computer automatic detection, recognition and target tracking. First of all, we can use the improved symmetrical frame differencing method to detect and remove snow. If the snow is intensive, we will remove snow fog to improve the result of restoration. The simulation results show that this method can effectively remove the snow in the video image, it can provide a feasible method for clearness of bad weather.
