摘要
讨论了数字图像增强技术中涉及到的直方图均匀化、对比度增强、平滑滤波、锐化等内容及用MATLAB的实现,同时还分别给出标准的数字图像在各种处理前与处理后的对照图像.
Several digital image enhancement techniques such as histogram equalization, contrast enhancement, smoothing filtering and sharpening are discussed in this paper. The detailed points for digital image enhancement processing based on MATLAB are presented at the same time. The contrasting images before and after processing of standard digital images are illustrated too.
