基于MATLAB的图像增强初探

在实际的生产、生活中,人们直接获得的原始图像并不能直接应用到生产、生活中。因为,原始图像在获取和传输过程中会产生各种噪声,造成图形的对比度不够、图像模糊、对所需要的信息,如边缘或线状地物不够突出等影响。针对上述问题,可以采用专业的图像处理软件进行处理。本文采用在MATLAB中,根据图像中存在的具体问题,利用MATLAB自带的函数以及用户自己编写的M函数解决具体问题。给出了用MATLAB进行灰度增强、直方图增强、平滑、锐化等操作及具体示例,通过这几个实验,取得较为理想的效果,达到了图像增强的目的。

Image enhancement based on MATLAB

In the actual production and daily life,people can not directly apply the original image to the production and life.This is because the original image will have all kinds of noise in the process of accessing and transmission.The noise causes the contast not enough,image penumbra,information what we need,such as marginal and linear features,is not prominent.Specific to the problems above-mentioned,we can use professional image processing software to process.But,the paper using MATLAB,according to specific issues,use MATLAB built-in functions and the user's own M function to solve specific problems.Specifically,this paper gives a demonstration of using MATLAB to complete gray enhancement,histogram enhancement,smooth,sharpening,and operating and specific examples.These experiments obtain quite ideal results,making the image enhancemented.
