Computer Vision Laboratory

Welcome to the Computer Vision Laboratory (CVL), part of the Department of Electrical engineer at Linköping University.

The research at CVL covers a wide range of topics within artificial visual systems (AVS): computational imaging, detection, tracking and recognition, geometry, robot vision and autonomous systems and medical imaging.

The design of AVS has its roots in the modelling of the human visual system (HVS); an extremely challenging task that generations of researchers have attempted with limited success. Vision is a very natural capability and it is commonly accepted that about 80% of what we perceive is vision-based. Vision's highly intuitive nature makes it difficult for us to understand the myriad of problems associated with designing AVS, in contrast to sophisticated analytic tasks such as playing chess.

Thus AVS became a widely underestimated scientific problem, maybe one of the most underestimated problems of the past decades. Many AI researchers believed that the real challenges were symbolic and analytic problems and visual perception was just a simple sub-problem, to be dealt with in a summer project, which obviously failed. The truth is that computers are better than humans at playing chess, but even a small child has better generic vision capabilities than any artificial system. CVL aims at improving AVS capabilities substantially, driven by an HVS-inspired approach, as AVS are supposed to coexist with - and therefore predict actions of - humans.

Research Areas

Robot Vision and Autonomous Systems

Machines that learn to visually perceive their environment and to interact with it.

Medical Imaging and Image Analysis

Geometry

Reconstruction of 3D points and motion trajectory of a vehicle moving in a traffic scenario.

Detection, Tracking and Recognition

Recognition and localization of objects in images and videos.

Computational Imaging

Modelling and correction of rolling shutter video.

For more information on our research, see the publications and projects sections of the website. CVL also provides weekly seminars and teaching activities for undergraduate and graduate students, including the possibility for master students to be involved in state of the art research with their master thesis.
