Technology and implementation of image enhancementabout bullet mark based on histogram mapping

ZHOU Ming zheng,WANG Jun(Dept. of Comp. Sci. & Engn., Anhui University of Technology and Science ,Wuhu 241000,China)  
Research on image enhancement is an important problem in image matching and recognition system about bullet mark. This article presents two kinds of arithmetic based on histogram to image enhancement. They are proportion and regulation process. Experiments show that they are effective to image enhancement. The regulation mapping group with a good histogram is especialy practical.
