In this course we will analyze the paradigm of automatic object recognition from a Computer Vision and Machine Learning points of view. We will review past and recent challenges in object recognition, such as multi-modal, multi-part, multi-scale, multi-view, multi-class, multi-label, and large scale object recognition. We will also review current trends for a particular and complex kind of objects: ‘people in visual data'. We will deal with the problem of human pose recovery and automatic behavior analysis, describing potential applications as well as future lines of research in the field.

Metodologia docent

T – Each week it will be a 1.5h theoretical topic exposition class.
P – Each week it will be a 1h practical session.
The rest of the course are devoted to autonomous lectures, programming, and studying.

Mètode d'avaluació

The course will follow a continuous evaluation consisting in four practical reports (PR) and two in-class presentations (PS). At the end of the course a test exam will be performed (TS). The final score (FS) will be computed as follows:
FS = 0.5 * PR + 0.3 * PS + 0.2 * TS
A minimum score of 3 over 10 points is required for each part PR, PS, and TS in order to compute the final score FS.
