Describing events

Activity Recognition using an ontology-base language

Participants: Carlos Crispim, Francois Bremond.

The page presents a general video understanding approach for the description and recognition of events occurring in videos, for real world (home-care) applications.

Here below are two videos showing 1) a raw video recorded at Thessaloniki pilot (the 4-activity protocol) and 2) the video processed with INRIA activity recognition system using as input a file describing the events to be recognized thanks to an ontology-base language defined in the team. The goal of this demonstration is for you to propose your own description of the events using the same langage.

Figure 1. Test Video from pilot in Thessaloniki dipicting an indivudal, who is performing various tasks of everyday life.

To describe which activity you want to recognize: Here is a file you can use to describe the activities
