Machine Vision

We are undertaking basic research on the analysis of motion, 3D reconstruction and image segmentation, with application to medicine, surveillance, document processing and virtual reality.

  

The group is developing robust algorithms for tracking non-ridgid objects, such as people, and for recognising events and actions (e.g. hand gestures). Together with basic research of 3D reconstuction and surface reflectance modelling, this research is aiming towards the constuction of environment models for use in telepresence and virtual reality. The School is a principal partner in the interdisciplinary Centre of Medical Imaging Research (CoMIR), in conjunction with the departments of Medical Physics and Statistics, and with scientists and clinicians from the major teaching hospitals in Leeds. Our work in CoMIR is currently concerned with the use of deformable models for the segmentation of medical images. Leeds is also a node in ECVNet, the EU Network of Excellence in Computer Vision.

The Machine Vision Group has its own home page, where you will find more detailed information about our activities.
