A Improved Method of Enhancement of Video Image in the Coal Mine
Meng Ling Zhao · Advanced materials research · 2012
Insufficient space and poor light down the coal mine resulted in many problems to the image on the monitor screen. In view of the problem of low resolution, unclear gradation, roughness and easy to interfere in the transmission process in bad communication environment, According to the characteristics of the image, researched to use the method of combining the algorithm of improving the traditional filter with the enhancement of contrast ratio to improve image. The experimental results indicate the method can make the underground video image quality improved and is a feasible method.
