Objectivies and Approach

The consortium plans to carry out a theoretical investigation of the potential behind non-linear diffusion in image processing. The aim is to realise efficient implementations and to bring the results to bear on important applications such as medical image enhancement. As an important spin-off, the consortium hopes to gain insight into the biological vision steps that follow the linear stages of the primary cortex.

The most important impact is expected to occur in the study of non-linear diffusion and regularisation processes which are at the basis of numerous visual and image-enhancing strategies. It is the aim of the consortium to contribute towards a mathematically rigorous and fundamental framework in which such processes can be understood and tuned to the requirements of the problems at hand.

Progress and Results

The progress made has resulted in more than 100 publications. A book entitled "Geometry-Driven Diffusion in Computer Vision" has been published by Kluwer in 1994. This is the first tutorial book in the field of anisotropic diffusion. This field, where the process of evolution of the image is a function of the image information itself, is rather new and a number of approaches to this process are currently developed.

Information Dissemination Activities and/or Exploitation

A DIFFUSION workshop, whose objective was the possibility of producing an axiomatic basis for vision, took place in Chapel Hill, USA, in November 1994.
