介绍一下图像增强技术的背景和意义以及现代图像增强技术发展的现状，其次是介绍图像增强技术的基本算法。由于要用到Matlab进行仿真，第三章将主要介绍Matlab软件在图像处理中的功能和运用。最后将详细的介绍直方图算法的意义、性质、显示及映射，并利用Matlab进行图像增强的仿真实现且达到了论文预期的目的和满意的实验结果。(Recommend the picture to strengthen the background , meaning and current situation of strengthening the technical development of modern picture of technology at first, secondly introduce the basic algorithm that the picture strengthens technology. Because should use Matlab and carry on emulation , chapter three will mainly introduce the Matlab software function and application in pattern process. Finally detailed introduction meaning, nature, showing and shining upon, histogram of algorithm, utilize emulation that Matlab strengthened the picture to realize and achieve the anticipated purpose of the thesis and satisfactory experimental result.)
