With the information age and the advent of the digital world, digital signal processing has bee an extremely important disciplines and technical fields. Current digital signal processing in munications, voice, image, automatic control, radar, military, aerospace, medical and household appliances and many other fields has been widely used. The course is designed to use MATLAB software to do image data analysis, including reading image and getting the images of the maximum, minimum, mean, median, and, standard deviation, two images of the covariance, correlation coefficient, etc. Key words: MATLAB，digital signal processing，image data analysis MATLAB的讀取方法 Matlab是解釋型語(yǔ)言，就是說(shuō)Matlab命令行中敲入的命令在當(dāng)前Matlab進(jìn)程中被解釋運(yùn)行。但是，每次執(zhí)行一個(gè)任務(wù)時(shí)敲入長(zhǎng)長(zhǎng)的命令序列是很煩人的。有兩種方法可以使Matlab的力量得到擴(kuò)展——腳本和函數(shù)。這兩種方法都用像emacs一樣的文本編輯器中編寫的m文件（，文件還稱點(diǎn)m文件）。m文件的好處在于它可以保存命令，還可以輕易地修改命令而無(wú)需重新敲入整個(gè)命令行。 新建m文件的方法為FileNewMFile。 從互聯(lián)網(wǎng)上下載圖片兩張，圖像為800*600和800*，如圖21和22所示 21 22Matlab顯示圖像的最基本的手段是使用image函數(shù)。該函數(shù)還產(chǎn)生了圖像對(duì)象的句柄，并允許對(duì)對(duì)象的屬性進(jìn)行設(shè)置，利用圖像讀取函數(shù)imread()可完成圖形圖像文件的讀取。 subplot函數(shù)介紹，在一般默認(rèn)的情況下，MATLAB 每次使用plot 函數(shù)進(jìn)行圖形繪制，將重新產(chǎn)生一個(gè)圖形窗口。但有時(shí)希望后續(xù)的圖形能夠和前面所繪制的圖形進(jìn)行比較。一般來(lái)說(shuō)有兩種方法：一是采用hold on(/off)命令，將新產(chǎn)生的圖形曲線疊加到已有的圖形上；二是采用 subplot(m,n,k)函數(shù)，將圖形窗口分隔成n*m
