Image processing

The group's research on image processing concentrates on the extraction of structural and symbolic features from colour, range and thermal images of 3-D objects. The symbolic features are in the form of an attributed relational graph. This describes the relations between contours of regions in a segmented image. Numerical attributes specify the colour ratios, position in image coordinates, invariant combinations of body centred moments, parameters of a best fitting plane (for plane-like surfaces).

Computer vision

The group's research on computer vision is mainly directed towards interpreting the structural features extracted by the image processing. Graph matching is the main tool for recognition. A particular interest as is the study of control strategies that are designed to prevent the matching becoming caught in the NP trap. A pilot system has been developed that exploits a coarse grained MPMD environment.

Separate research has developed a system for inspection of foodstuffs that is based on the processing of transmitted infra-red and the comparison of the resulting image with a structural model of the foodstuff being inspected. The system has been applied to the inspection of live crabs and a patent has been obtained.

The group's research on graphics is mainly designed to support the research on computer vision through a study of modelling techniques to create reference objects for object recognition from CAD/CAM and raytracing models.

Virtual reality

The group's research on virtual reality is centred on the creation of realistic models of the ancient city of Trondheim in time for the 1000 th. year of the city in 1997.
