It bines numerical analysis, matrix putation, signal processing and graphical display on the whole, constitute a convenient, userfriendly user environment, but also has the scalability characteristics.MATLAB is a vector language is very suitable for image processing, its builtin digital image processing toolbox, including 15 class functions in support of four kinds of image types, and can be interchangeable, ATLAB operable image files, including BMP, HDF, JPEG , PCX, TIFF, XWD and other formats. This article describes the characteristics of the language of the MATLAB image processing toolbox to achieve the classic image processing technology. Presented an overview on the basic operation of the image, as well as images FFT transform, DCT transform, SVD transform, QR transform, wavelet transform.Through an image through the MATLAB image toolbox box imread。wavedec2等圖像矩陣變換函數(shù),進(jìn)行處理,能大致基本展示MATLAB對圖像處理方面的強大功能。 svd。 dct。 figure等基本圖像處理函數(shù)以及fft。imshow?？傮w介紹了,對圖像的基本操作,以及對圖像進(jìn)行FFT變換,DCT變換,SVD變換,QR變換,小波變換等。MATLAB是一種向量語言,非常適合于圖像處理,其自帶的數(shù)字圖像處理工具箱包括15類函數(shù),支持四種圖像類型,并可相互轉(zhuǎn)換,ATLAB可操作的圖像文件包括BMP、HDF、JPEG、PCX、TIFF、XWD等格式。時間安排: 指導(dǎo)教師簽名:年月日系主任(或責(zé)任教師簽名:年月日目錄摘要..........................................................
