How to hand in a homework assignment
Any written parts of an assignment should be answered in a text file, if possible,
and turned in to the hand-in directory as a Readme.txt or Readme.pdf file.
Include on the top of the front page your name, login, HW #, date and,
if late, how many days it is late.
Electronically hand in files containing the MATLAB code you wrote for the assignment and
all image results you obtained.
Copy each file to the designated assignment's hand-in directory. For example, for Homework #1, do (in Linux):
ls -l /p/course/cs534-dyer/handin/your-cs-login-name/HW1/
Be sure to also save a separate copy of your completed code and result images in your
own private directory as a backup to the copy you put in the hand-in directory.
Do not alter your own copy after you turn it in so that the date on the file
is the same as the date of what you hand in.
Note: All parts of each assignment are all due on the due
date at the due time.
Late Penalties:
All assignments are due on the due date by 11:59 p.m.
One (1) day late, defined as a 24-hour period from 11:59 p.m.
to 11:59 p.m. the next day (weekday or weekend), will result in 10% of the
maximum points for the assignment
deducted. So, for example, if an assignment is due on a Wednesday and it is
handed in any time on Thursday, a 10% penalty will
be deducted. Two (2) days late, 25% off; three (3) days late, 50% off.
No homework can be turned in more than three (3) days late.
A total of two (2) free late days may be used throughout the
semester without penalty.
Corrections of any grading problems must be resolved within one week after a homework is handed back.
Homework #1: Creating 3D Models, Panoramas, and HDR (Due: Monday, September 19)
Photomatix is installed on the Windows machines in the Starsky/Hutch Lab in room 1358 CS; other instructional Windows machines will have the trial version of Photomatix installed, which adds a watermark to images you create.
You may also get a free copy of this trial version for installation on your home Windows or Mac machine.
Turn in your result images
to the HW1 hand-in directory at /p/course/cs534-dyer/handin/your-cs-login/HW1/
Homework #2: Image Processing in MATLAB (Due: Friday, September 30)
Use as your second test pair two images of your choice
Hand-in Instructions
Turn in your MATLAB files, and input and output result images to the HW2 hand-in directory at
/p/course/cs534-dyer/handin/your-cs-login/HW2/
Put everything associated with each problem in a separate folder.
For example, put all of your code and results for problem 1 in a folder called "P1" and then copy it
to the hand-in directory for HW2 as follows:
cp -r P1 /p/course/cs534-dyer/handin/your-cs-login/HW2/
You can verify what files were submitted by doing:
ls -l /p/course/cs534-dyer/handin/your-cs-login/HW2/P1
Homework #3: Image Resizing using Seam Carving (Due: Friday, October 14)
Run your code on the image union-terrace.jpg with the parameters given in the assignment.
In addition, find on the web or shoot your own photos to use at least 2 additional images,
one which shows a good result and one that shows a poor result.
Homework #4: Panoramic Image Stitching (Due: Monday, October 31)
Readings
Material related to this assignment is given in the lecture slides, the paper

and in parts of the following sections in the textbook: 2.1.2, 4.1.1., 4.1.2, 6.1.2 - 6.1.4, 9.1.1, and 9.3.2.
Tentative title, team members, and abstract: Wednesday, November 23
Turn in to your HW5 handin directory a file named <short-title>.txt that uses the following html template for entering your project info:
<LI><B>name1</B> and <B>name2</B><BR>
<I>title</I><BR>
abstract

Final Paper and Web Page: Wednesday, December 21
Include at the end a description of what code you got from elsewhere that you did not write, and what code your team wrote; include approximate number of lines of code written. Also describe what the main contributions were of each team member. Hand in your report electronically to one person's handin directory.
Places to Look for Project Ideas
Look for inspiration from works of art, visual perception, visual illusions, physics of light, interesting categories of images on photo sharing sites, etc.
Running MATLAB and other Programs Remotely
For students who are Engineering majors or are taking a course this semester in Engineering, you
may be able to get MATLAB for a home machine via a tethered copy in CAE.
For more information, see
MATLAB Tethered Installation for Windows or
MATLAB Tethered Installation for Mac OS X
If you want to run MATLAB or any other program installed on one of the CS Department Linux machines
remotely from your own computer at home, here is how you can do it:
From any Mac OS or Unix OS machine:
Type in the following command in a terminal window on your laptop:
ssh -X <your-cs-login>@best-linux.cs.wisc.edu
You will be prompted to enter your CS login password and then a secure connection
will be started on a CS Linux workstation.
Install Xming and the fonts package in the same folder by double-clicking
the .exe files that you downloaded in Steps 2 and 3.
Go to the Start Menu and run XMing. If you are using a firewall, it will ask if you
want to unblock it. You don't need to. Look for the "X" icon in your system tray. Hover the mouse
over it: it should say something like "Xming server - 0:0". The last bit
should be "0:0", but if it's not, pay attention to that and use it in the
subsequent steps as directed.
Run putty.exe, the file that you downloaded in Step 1.
In the window that pops up under host name, enter
"<your-cs-login-name>@best-linux.cs.wisc.edu". Then, on the left, click on the
Connection/SSH/X11 sub-panel. It'll have a few options. Check "Enable X11
Forwarding", and in the "X display location", put "localhost:0:0" in the
box (unless you didn't have "0:0" in Step 5 above: then use
"localhost:x:y", where "x:y" is whatever you saw on the icon). Leave the
radio button on "MIT-Magic-Cookie-1". Now click back to the main "Session"
panel on the left. Put a name (any name like "cs") in the text box in the
middle right below "Saved Sessions". Click the "Save" button. From now on,
you can double click the connection in the list box when you want to
connect; you don't need to configure these settings every time. Press "Open" to
start PuTTY. Put in your CS assigned username and password. Now run the
command xeyes &. You should get a big pair of googly-eyes that follows
the cursor around. It works!
