Matei MANCAS holds an ESIGETEL Audiovisual Systems and Networks engineering degree (Ir.), and a Orsay Univ. D.E.A. degree (MSc.) in Information Processing. He also holds a PhD in applied sciences from the FPMs on computational attention since 2007.

His research deals with signal saliency and understanding.

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.

Matei is now the SmartSpaces Group leader @ the Numediart Research Institute (UMONS Institute for Creative Technologies)

Current research

Matei focuses on the 1) prediction, 2) analysis and 3) trigger of human attention. Attention is the process used by humans to focus on "important" features in images, videos or sounds and it is the beginning of a higher level signal understanding. Attention is also directly related to motivation which leads to action. Part of this research is done for artistic purposes within the Numediart Research Institute (UMONS Institute for Creative Technologies).

  • Attention prediction: More on computational attention can be found at this dedicated page.



  • Attention analysis: Attention-related non-verbal signals extraction using RGBD sensors (head and body orientation, emotions, expressive gestures and poses, interpersonal spaces).



  • Attention trigger: Serious game-based interactions and emergent gameplays enhancing attention and motivation.



Matei visited for several months the Alcor Lab of the Sapienza University (Rome) and IRISA Lab of the University of Rennes (France) and he is interested in bringing attention algorithms into real-life and real-time in several application domains:

  • People interest for marketing optimization
  • Audio-video event detection for surveillance
  • Abnormal behavior detection in crowd videos for video-surveillance or crowd augmentation
  • Images and medical images saliency
  • Small interacting groups of people using 3D saliency (from RGBD sensors) and audio event integration for serious social games and artistic applications
  • Saliency of human gestures and proxemics
  • People interest analysis using non verbal cues (head/body)
  • Saliency algorithm embodiment in pan-tilt mechanical systems

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

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