Images and Video Processing Laboratory (LITIV)

École Polytechnique de Montréal, Montréal, Québec
What the facility does

Research in the fields of imaging and video surveillance in the visible and infrared spectra.

Areas of expertise

The laboratory develops methods and algorithms for automatic detection and tracking of actors (people and vehicles) that are visible in a camera’s field of view. It focuses on instances where the actor to be detected is considered known at first sight or where the actor is considered unknown or unexpected. LITIV has unique experience in using infrared cameras and visible spectrum cameras for video surveillance applications. It also specializes in video surveillance by pan-tilt-zoom (PTV) camera.

Research services

LITIV’s research services focus primarily on developing image processing algorithms, detection and tracking algorithms, and algorithms for measuring temperatures with thermographic cameras. 

Sectors of application
  • Defence and security industries
  • Healthcare and social services
  • Information and communication technologies and media
  • Life sciences, pharmaceuticals and medical equipment
  • Transportation
