在图像处理过程中，使用直方图均衡化、全局对比度拉伸等基于图像全局信息的图像增强算法，难以实现图像局部细节对比度的增强，即不能实现物体轮廓的增强。为此，本文主要对基于局部直方图均衡化、Lee算法的图像局部增强算法和MSR算法进行研究，通过算法的改进来实现图像局部增强的效果。

In the process of image processing, using the histogram equalization, the global contrast stretching the image en-hancement algorithm based on global information , it is difficult to achieve the image local contrast enhancement , that is cannot a-chieve the object contour one.Therefore, in this paper our research on local enhancement algorithm and MSR algorithm is based on the main image local histogram equalization, Lee algorithm.By the improvement of the algorithm, we get the local image enhance-ment effect.
