This course will introduce the students to techniques for action recognition and tracking in videos. The first few lectures offer recalls of foundational topics such as probability, Bayesian classification and density estimation which will facilitate the comprehension of the following topics. Action classification covers the hidden Markov model, bag-of features approaches and conditional random fields. Tracking covers recursive Bayesian estimation and the Kalman and particle filters. The course aims to be of benefit for research students in the areas of computer vision, pattern recognition, multimedia, image and signal processing, human-computer interaction, and also computer science/computer engineering in general.


Learning modalities

The course will be taught over 4 days in eight slots, two slots per day with a break in between. The presentation will be based on slides and occasional use of whiteboard. The course can be taught in either Italian or English at the preference of the convenor.

All materials for the course will be in English. A copy of the slides will be provided to the students. The copyright of all materials stays with the copyright holders.
