基于matlab的数字图像信息处理降噪滤波

README file for the DIPUM Toolbox. These MATLAB functions were created for the book Digital Image Processing Using MATLAB (DIPUM), by R.C. Gonzalez, R.E. Woods, and S.L. Eddins, Prentice Hall, 2004, ISBN 0130085197. The functions supplement and extend the image processing functionality of MATLAB and the Image Processing Toolbox, both offered by The MathWorks. The free version of the DIPUM Toolbox ------------------------------------- The free version of the DIPUM Toolbox contains only executable MATLAB P-files. P-files may be executed as MATLAB functions just as M-files. Unlike M-files, however, neither the help text nor the source code is accessible. Complete source code listings for all functions are included in the book. The registered version of the DIPUM Toolbox ------------------------------------------- The registered version of the DIPUM Toolbox contains M-files with readable source code and help text. Users who want the M-files in electronic form may obtain, for a small fee, a password allowing them to download the registered toolbox. More information about obtaining the registered toolbox version is available at the book's web site: http://www.imageprocessingbook.com/index_dipum.htm Requirements ------------ This initial release of the DIPUM Toolbox was developed and tested using MATLAB 6.5 and the Image Processing Toolbox 3.1. The DIPUM Toolbox is not supported for use with earlier versions of MATLAB or the Image Processing Toolbox. Most DIPUM functions require the Image Processing Toolbox. The DIPUM Toolbox works with all MATLAB platforms. It includes one MEX-file (UNRAVEL, which is used for Huffman decoding). Compiled binaries for this MEX-file are provided for all MATLAB platforms. Installation ------------ To install the DIPUM Toolbox, place the folder containing the functions on a local hard drive or a network drive accessible to your computer, and then include the folder location in the MATLAB path. To set the MATLAB path, start MATLAB and then select the File/Set Path menu item. Then select Add Folder. Use the navigation window to select the folder containing the functions. Click OK and then click Save. The functions will then be ready for use within MATLAB. Copyright --------- The DIPUM Toolbox is protected under U.S. and international copyright law. You may not transfer, publish, disclose, display, or otherwise make available either the free or the registered versions of the DIPUM Toolbox to other people. In particular, you may not place either version of the DIPUM Toolbox on an Internet site, a computer bulletin board, or an anonymous ftp directory from which it could be downloaded or copied by other people. Anyone may obtain the free version directly from the book's web site. Disclaimer of Warranty ---------------------- The DIPUM Toolbox source code is furnished "as is." Neither the authors nor the publisher of Digital Image Processing Using MATLAB make or imply any warranties that the DIPUM Toolbox software is free of error, that it is consistent with any particular standard of merchantability, or that it will meet your requirements for any particular application. The authors accept no responsibility for any mathematical or technical limitations of the functions that make up the DIPUM Toolbox. The DIPUM Toolbox should not be relied upon for solving a problem whose incorrect solution could result in injury to a person or loss of property. Neither the authors nor the publisher of Digital Image Processing Using MATLAB shall in any event be liable for any damages, whether direct or indirect, special or general, consequential or incidental, arising from use of the DIPUM Toolbox. The DIPUM Toolbox was not created by The MathWorks, nor is it supported by The MathWorks.
