README file for the DIPUM Toolbox.

These MATLAB functions were created for the book Digital ImageProcessing Using MATLAB (DIPUM), by R.C. Gonzalez, R.E. Woods, andS.L. Eddins, Prentice Hall, 2004, ISBN 0130085197. The functionssupplement and extend the image processing functionality of MATLABand 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 executableMATLAB P-files. P-files may be executed as MATLAB functions justas M-files. Unlike M-files, however, neither the help text nor thesource code is accessible. Complete source code listings for allfunctions are included in the book.

The registered version of the DIPUM Toolbox-------------------------------------------The registered version of the DIPUM Toolbox contains M-files withreadable source code and help text. Users who want the M-files inelectronic form may obtain, for a small fee, a password allowing themto download the registered toolbox. More information about obtainingthe registered toolbox version is available at the book's web site:

http://www.imageprocessingplace.com/DIPUM/dipum_m_files/dipum_toolbox.htm

Requirements------------This initial release of the DIPUM Toolbox was developed and testedusing MATLAB 6.5 and the Image Processing Toolbox 3.1. The DIPUMToolbox is not supported for use with earlier versions of MATLAB orthe Image Processing Toolbox. Most DIPUM functions require theImage Processing Toolbox.

The DIPUM Toolbox works with all MATLAB platforms. It includes oneMEX-file (UNRAVEL, which is used for Huffman decoding). Compiledbinaries for this MEX-file are provided for all MATLAB platforms.

Installation------------To install the DIPUM Toolbox, place the folder containing thefunctions on a local hard drive or a network drive accessible toyour computer, and then include the folder location in the MATLABpath. To set the MATLAB path, start MATLAB and then select theFile/Set Path menu item. Then select Add Folder. Use thenavigation window to select the folder containing the functions.Click OK and then click Save. The functions will then be ready foruse within MATLAB.

---------The DIPUM Toolbox is protected under U.S. and international copyrightlaw. You may not transfer, publish, disclose, display, or otherwisemake available either the free or the registered versions of the DIPUMToolbox to other people. In particular, you may not place eitherversion of the DIPUM Toolbox on an Internet site, a computer bulletinboard, or an anonymous ftp directory from which it could be downloadedor copied by other people. Anyone may obtain the free versiondirectly from the book's web site.
