Vision, Graphics and Visualisation

There is a significant computer vision component within the IRG group, including: feature-based localisation of aerial platforms for planetary exploration; extraction of the 3D structure of complex objects; EPSRC-funded work on appearance-based methods to provide mobile robots with various capabilities including topological mapping and pose stabilisation. These areas have recently led to additional funding covering vision aspects in planetary science and topological data analysis.

Our vision research has gone beyond a supporting role for robotics, reflected in the Department’s recent strategy to further develop the vision research sub-group. Texture analysis and synthesis is used in image manipulation and medical image understanding: developments in the topological aspects of the domain are supported by EPSRC funding and are leading to improved understanding of human image evaluation. Registration has concentrated on computational geometry and other mathematical properties of images and volumes, recognition of articulated motion for evaluating human walking patterns, and medical shape analysis.
