Course Description

This course will focus on inference with statistical models for image analysis. We use a framework called probabilistic graphical models which include Bayesian Networks and Markov Random Fields. We apply the approach to traditional vision problems such as image denoising, as well as recent problems such as object recognition. The course covers amongst others the following topics:

Time and Place

Lectures 10-12, 13:00-15:00 Informatik, Seminarraum 205

Paper presentations: Should be in groups of 2 or 3 and should be 20 minutes in length. There will also be time for discussion after each presentation.

New (29 August 2013): Lecture 9 slides available.

Matlab

The official Matlab documentation is available online at the Mathworks website (also in printable form). If you have trouble accessing Matlab's built-in help function, you can use the online function reference on that page or use the command-line version (type help <function> at the prompt). There are several primers and tutorials on the web, a later edition of this one became the book Matlab Primer by T. Davis and K. Sigmon, CRC Press, 2005.
