An Improved Algorithm of Histogram Equalization to Increase Brightness of Image in Mine

Abstract:

To improve the contrast ratio and brightness of video surveillance image in mine, we modify the histogram equalization algorithm by extent the boundary when calculating the sum of gray probability. Experimental results show that the algorithm can reserve the characteristics of the histogram equalization and improve the image’s brightness.
