Matei MANCAS

Research:

Current research

Matei focuses now on Computational Attention. This mechanism is used by humans in order to select "important" features in images, videos or sounds and it is the beginning of a higher level signal understanding. Matei assumes that computational attention is a step towards true artificial intelligence and it should be used in every algorithm which intends to have an intelligent behaviour.

Matei visited for several months the Alcor Lab of the Sapienza University (Rome) during the end of 2010 and he is interested in bringing attention algorithms into real-life and real-time for diverse applications:

• Audio event detection for surveillance
• Images and medical images saliency
• Abnormal behavior detection in crowd videos for video-surveillance or crowd augmentation
• Small and interacting groups of people using 3D saliency (from Kinect sensors) and audio event integration for serious social games and artistic applications
• Saliency of human gestures and proxemics
• Saliency algorithm embodiment in pan-tilt mechanical systems

More details on Computational Attention can be found on this dedicated page. Part of this research is done for artisitic purposes within the NumediArt institute.

Tools for research

For validation and research purposes we have a web-based platform for mouse-tracking where people can login and their mouse position on the screen is recorded and aggregated into interestingness maps: http://tcts.fpms.ac.be/~mousetrack. Recently, we acquired a FaceLab 5 eye-tracking device.

Past research

Matei's past research interests concern signal and, in particular, image processing. After a study on nonstationary shock signals in industrial tests at MBDA, he worked on medical image segmentation and set up an original iterative watershed segmentation technique.

A demonstration of the Iterative Watershed Segmentation method is currently online.

A copy of an article published on the study of nonstationary shock signals in industrial tests at MBDA is available in the publication list.
