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 puting and graphics display capabilities, so that image processing bees more simple and intuitive. This paper introduces characteristics of MATLAB language and this MATLABbased 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,2numeric image and other image processing technologies.Key words：MATLAB, digitalimageprocessing,The statistic image coding,Huffman code第 17 頁 共 19 頁
