摘　　要：研究了空间域下基于直方图处理的图像增强算法。通过直方图统计获得具体参数,根据平均值和方差调整图像的强度和对比度,以实现对图像的增强。由于对图像进行全局增强,不能有效突出局部特征,因此重点阐明局部图像增强的算法。试验结果表明,该算法可以有效增强图像的局部细节。This paper studies the image enhancement algorithm based on the histogram processing in the spatial domain.Specific parameters are obtained according to the histogram statistics.In order to enhance an image,the intensity and contrast of the image is adjusted on the basis of the mean value and variance.It is considered that the global image enhancement doesn't have the function of standing out the local features.So this paper mainly researches the local image enhancement algorithm.Experimental results show that the algorithm can enhance the local details of image effectively.
