Computer spots behaviour patterns

Applications for the system could include intelligent surveillance and accident prevention.

HERMES (Human Expressive Graphic Representation of Motion and their Evaluation in Sequences) analyses human behaviour based on video sequences captured at three different focus levels: the individual as a relatively distant object; the individual’s body at medium length so as to be able to analyse body postures; and the individual’s face, which allows a detailed study of facial expressions.

The information obtained is processed by computer vision and artificial intelligence algorithms, which permits the system to learn and recognise movement patterns.

HERMES is said to offer two important innovations in the field of computer vision. The first is the description of, in natural language, movement captured by the cameras, through simple and precise phrases that appear on the computer screen in real time, together with the frame number in which the action is taking place. The system uses an avatar to talk and describes this information in different languages.
