Introduction
Homework assignments
throughout the course will be written in MATLAB. Matlab is a C-based
interpreter. The basic structures in Matlab are vectors and matrices and as
such Matlab is appropriate for Image Processing.
Where Do I find Matlab?
At Univeristy of
Haifa, Matlab is available on the PCs in
the computer labs. Matlab can be installed on your home computer if you
have a licensed package. You can use a student version of Matlab (which are not
expensive).
Matlab Manuals and Reference Guides are available in the library. Very good tutorials are also available on the
web (see relevant resources
below). If all else fails, there is
always the "help" command in Matlab.
How do I start Matlab?
On the lab PCs : Find the Matlab Icon.
Double clicking on the icon will start the Matlab environment.
A shell window with the ">" prompt will be opened. This is the command
line.
You can also start Matlab by double clicking on a matlab file (XXX.m) in which
case the Matlab environment will start and a editor/debugger window will be
opened with the file.
How do I work with Matlab?
The recommended way
of working in Matlab is to open Matlab in one window and open the Matlab editor
in another window. Select commands in the editor then press F9 (run). This way
you can rerun commands, discover your errors, and interactively build your
scripts and functions (don't forget that Matlab is an interpreter based
language). The Matlab environment provides an editor/debugger which
checks syntax and can run the edited file.
Can I use Matlab Toolboxes?
Mathworks also
provides toolboxes which are a collection of functions associated with a
specific topic. Relevant toolboxes might include: image processing toolbox,
signal processing toolbox, optimaization toolbox, etc. However you must obtain
instructors permission to use functions from these toolboxes in your
assignments. typically, assignments should be based on standard Matlab
functions (not in toolboxes).
You may use the Image processing function used in the Image processing Course
at U of Haifa.
What do I hand in as homework?
In the homework
assignments you will have to write "programs" in Matlab. In practice
this will usually mean to write a function (an m-file). Your function may call
other functions which you have created. Your homework will be evaluated
interactively by calling your function with various inputs.
How do I hand in homework?
Since homework
checking will be performed interactively you will have to submit all m-files
associated with your homework. Homework will be submitted on CDs or via
email (as directed by your instructor). Make sure student names and i.d. are clearly
marked.
How will homework be graded?
Checking will be
interactive. Points will be given per correct output for each input. The
efficiency of your algorithm will be checked as well. Try to avoid loops in
your program if Matlab enables it. Points will also be given for
clean and well documented m-files!!! Make sure you write documentation
at the head of each function/file and also in the midst (see example m-files).
Make sure your Names and Student I.D.s are also in the documentation at the
head of the file. Homework must be submitted ON TIME. Penalty points
(10) will be deducted for every day beyond the deadline.
