基于MATLAB图像增强处理技术的研究

本文介绍了一种基于MATLAB的可视化图像增强处理技术，并对这一技术的需求分析与设计，所需的开发工具，软件实现，所需主要代码设计与典型窗口示例作了相应介绍。
本论文着重介绍了常用的图像增强处理技术的方法，主要包括直方图均衡化和规定化，中值滤波，小波去噪技术，并给出相关的基本原理。同时用MATLAB语言加以实现，并且用实例说明了处理前后的对照图像。最终从结论中得出图像增强处理技术在数字图像处理技术中的应用价值。

Research of Image Enhancement Technology
based on MATLAB
Abstract
      This paper introduces a visualization of image enhancement processing technology based on MATLAB。It explains the design of this technology, the necessary development tools, software, code requirements for the design of the main window with the typical sample introduction.
The paper first introduces the nomal technique of image enhancement，including the image histogram balancing and histogram provision to turn a image to build up technique，median filter, wavelet denoising and give related basic principle。These methods carries out with the MATLAB language in the meantime，and gave a contrast images before and after treatment。At last，we know the image enhancement processing technology will get useful vlaue in the digital image processing technology from the conclusions。
Keywords: MATLAB，image enhancement，histogram，median filter，wavelet denoising
