From Computer Vision at Western
Welcome to the Computer Vision Research Group at the University of Western Ontario.
Our group has a strong history in low-level image analysis problems such as optical flow, stereo, segmentation and tracking. More recently we've tackled problems in multi-view reconstruction, real-time robot vision, Markov Random Field optimization, and much more. To find out more about ongoing research, browse through the interests of the people involved.
Our students and faculty have access to state of the art computing facilities such as Sharcnet and new hardware and labs built specifically for computer vision research. Throughout much of the year we hold seminars to discuss recent developments in computer vision (pizza lunch + video lecture or presentation by one of our members/guests). Vision group members can read more about resources in the main vision lab, located in the Western Science building.
Recently offered graduate courses on computer vision include:
- CS9645: Introduction to Computer Vision
- CS9630: Image Processing and Analysis
- CS9687: Algorithms for Image Processing, Medical Imaging and Computer Graphics
- CS9840: Computer Vision and Learning
- CS9837: Vision for Graphics
