Computer Vision (6 ECTs)

Cameras are everywhere: phones, driving cars, hospitals, cinema, … even cleaning robots have one! But how do you go from raw pixel values into meaningful information? Where is the face in the image? Is there a pedestrian ahead? What is the 3D shape of the tumor in this lung? How do you add a virtual character into a real 3D scene?

This course provides a travel accros the field of Computer Vision: it starts at the basic concepts of light, color and camera devices and ends with cutting edge approaches recently published in the main scientific conferences of the domain. The course combines general technological basic concepts, theoretical mathematical fundations as well as practical sessions. In addition, as the Computer Vision field is in constant and rapid evolution, the course provides an emphasis on reading and understanding scientific papers.
