Audience: This course is
intended for advanced undergraduate and beginning graduate students
in pursuing research in AI, Vision or related areas. Students
should expect to do a fair amount of independent study, both in
following the material and completing a course project.
The grades are based
on a small number of assignments (4) and a project. For the
students will choose a vision problem or application, implement one or
more algorithm(s), and prepare a final report. The grades awarded
will depend on the difficulty of the problem selected, the
implementation effort, and the report. The report should provide
sufficient experiments and analysis, in particular, situations where
the algorithm(s) work and where they fail.
students will take on a more advanced project, either from a recent
or vision-related topics from their thesis area.
assignments, 50% project. Assignments will typically have a both
a written and a (small) programming component.
This is a lecture-based course. Material will be presented on the
blackboard and supplemented with
images and video. For those who do not wish to copy notes, I will
appoint a note taker who will make lectures available after each
Software: Matlab will be used for
is encouraged for the project. Matlab is available in the
Undergrad Computing Enviroment. Matlab is an interactive
language, with a C-like syntax, that is optimized for numerical
computation and plotting/graphics.
- Software Licensing:
The Matlab license is expensive and restrictive. For those
interested in Open Source software, Octave provides a
substitute for the assignments, albeit with bit of extra user
effort. The main difference between Octave and Matlab is in
plotting (Matlab is nicer). Matlab also has several specialized
"toolboxes" (image processing, signal
processing, etc) that Octave does not have. These change
frequently, and require additional licensing, so assignments in this
course will avoid toolboxes to maximize portability of code.
Prerequisites: There are no formal prerequisites for this
is advisable to have some exposure to numerical computation, especially
algebra (eg., CS370), and some basic programming experience.

even if you plan an ambitious project. You can always add to it later.
