Contents: A.zip: code compatible with Matlab 2007a and older B.zip: code compatible with Matlab 2007b and newer data.zip: test data instructions.pdf: this file Instructions: Unzip the selected file (A.zip or B.zip) in Matlab current directory (C:/.../Matlab/work is the default one). Type the name of main function on Matlab command window. Now a simple and intuitive GUI should appear. You can use images/data present in data.zip: just unzip them in Matlab current directory.
