Research

NSERC Discovery research program

We focus on the development of novel methods to improve decision making abilities of intelligent video surveillance systems. By intelligence, we mean to assist humans and reduce cognitive overload by automatically extracting relevant information and detecting suspicious events in security applications. Our long-term goal is thus to develop solutions to better understand monitored scenes, through the efficient exploitation of computer vision methods and visual acquisition technology.
