Computer Vision Laboratory

The laboratory is involved in basic research in computer vision, trying to extract as much information from pictorial material as possible, with emphasis on object segmentation, recognition and tracking, face detection, face and iris recognition, panoramic imaging, texture processing, range image interpretation, real-time and multimedia applications.

Analysis and tracking of objects in video sequences is applied to studies of human locomotion, roulette gaming instruments and golf. Superquadric models are also used for object tracking in sequences of intensity images.

Biometry is an important research field for us. For human face detection and recognition in difficult illumination conditions, we study the use of skin colour and appearance and fusion of different techniques. Lately we are also interested in use of such techniques in smart advertising, digital signage. In 2008 we also implemented our first test system for iris recognition.

We generate panoramic images in different ways and for different purposes: for depth reconstruction, for mobile robot navigation, for designing efficient user interfaces, for visual surveillance applications.

Possible applications of range image interpretation include automatic creation of CAD models for reverse engineering applications, creation of models for virtual reality applications, and part-based object recognition.

Real-time quality control of products in the production line is another area of research.

An ongoing collaboration with the New media department of the Academy of Fine Arts at the University of Ljubljana supports the creation of interactive art installations using the latest information technology. The art projects serve as an excellent frame for testing our research results in practical applications, in particular, we applied face detection in the installation "15 seconds of fame", body position tracking in "Virtual skiing" and locomotion-based person identification in "Coincidence-matrix-dating club" project.

Use of unconventional user interfaces based on computer vision in computer games is also of our interest. In 2008 we established a GameTeam within the laboratory with a number of student members working on projects like 3D Maze, Bubbles and Virtual Painter.

From the applicative point of view we are especially interested in biometry systems, image based computer forensic, gaming systems, quality control of products, surveillance applications and smart advertising.

More details about the research and development done in the laboratory are given in the following sections, especially in the Research Projects section and Selected Publications section.
