Image enhancement based on MATLAB

CHENG Fei,ZHANG He-sheng(Taiyuan University of Technology,Taiyuan 030024,China)  
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.
