Abstract
Digital image processing is an emerging technology, with the development of computer hardware, real-time digital image processing has become possible due to digital image processing algorithms to appear, making it faster and faster processing speed, better for People services .Digital image processing is used by some algorithms computer graphics image processing technology. Digital image processing technology has been in various areas have a relatively wide range of applications. Image processing large amount of information on the processing speed requirement is relatively high. MATLAB powerful computing and graphics display capabilities, so that image processing becomes more simple and intuitive. This paper introduces characteristics of MATLAB language and this MATLAB-based digital image processing environment, describes how to use the MATLAB Image Processing Toolbox for its digital image processing, and through some examples to illustrate the use of MATLAB Image Processing Toolbox for image processing method. Mainly discusses the use of MATLAB for image enhancement and other image processing technologies.
Keywords: MATLAB, digital image processing, image enhancement.
