MATLAB 6.5 Image Processing Toolbox Tutorial The purpose of this tutorial is to gain familiarity with MATLAB’s Image Processing Toolbox. This tutorial does not contain all of the functions available in MATLAB. It is very useful to go to Help\MATLAB Help in the MATLAB window if you have any questions not answered by this tutorial. Many of the examples in this tutorial are modified versions of MATLAB’s help examples. The help tool is especially useful in image processing applications, since there are numerous filter examples. 1. Opening MATLAB in the microcomputer lab 1.1. Access the Start Menu, Proceed to Programs, Select MATLAB 6.5 from the MATLAB 6.5 folder --OR-- 1.2. Open through C:\MATLAB6p5\bin\win32\matlab.exe 2. MATLAB 2.1. When MATLAB opens, the screen should look something like what is pictured in Figure 2.1, below. Figure 2.1: MATLAB window 2.2. The Command Window is the window on the right hand side of the screen. This window is used to both enter commands for MATLAB to execute, and to view the results of these commands. 2.3. The Command History window, in the lower left side of the screen, displays the commands that have been recently entered into the Command Window. 2.4. In the upper left hand side of the screen there is a window that can contain three different windows with tabs to select between them. The first window is the Current Directory, which tells the user which M-files are currently in use. The second window is the Workspace window, which displays which variables are currently being used and how big they are. The third window is the Launch Pad window, which is especially important since it contains easy access to the available toolboxes, of which, Image Processing is one. If these three windows do not all appear as ta
