Research interests

The general objective of my research is to design methods and algorithms to interpret the action occurring in a scene. The informations of interest are the interactions between humans and the interactions between humans and the objects in their environment. The use of visible cameras allows identifying some interactions in some circumstances, but in the case of similar colors between the scene and human in it, the analysis becomes quite difficult. I am proposing to use infrared cameras to introduce thermal information in the analysis of the scene.

My research projects thus aim to integrate information from visible and infrared cameras to improve the detection of humans and objects, along with their interactions.

A second topic of interest of professor Bilodeau is tracking with (pan-tilt-zoom) PTZ cameras. The interest in using such a camera is a larger coverage of a scene with a single camera. Controlling the camera to perform accurate tracking is the challenge that we are undertaking.

Finally, professor Bilodeau is also interested in the contribution of infrared cameras to medical experiments. Infrared, more specifically thermography, allows obtaining temperature measurements in real-time of the body of a subject. Our project aims to improve the measurements.

Biography

Guillaume-Alexandre Bilodeau received the B.Sc.A. degree in computer engineering, his M.S. and Ph.D. degree in electrical engineering from Université Laval in Canada, in 1997, 1999 and 2004, respectively. In 2004, he was appointed Assistant Professor at École Polytechnique de Montréal, and Associate Professor in 2011. Since 2014, he is a Full Professor at the same institution. In 2002, he received an Honorable mention for the Twenty-ninth annual Pattern Recognition Society award for his paper entitled "Part segmentation of objets in real images" in the journal Pattern Recognition. Since 2006, he is a member of the steering commitee and of the thematic committee of the REPARTI center. In 2008, he received the best vision paper award at the Canadian Conference on Robot Vision (CRV).  In 2011, he was the general chair of IEEE Symposium on Robotic and Sensor Environments. From june to november 2012, Dr. Bilodeau was Visiting Professor at the School of Electrical Engineering and Computer Science at University of Ottawa. In 2014, he was local arrangements chair for AI/GI/CRV.

His research interests encompass image and video processing, video surveillance, object recognition, content-based image retrieval, and medical applications of computer vision.

Dr. Bilodeau is a member of the Province of Quebec's Association of Professional Engineers (OIQ) and of the Institute of Electrical and Electronics Engineers (IEEE)
