Many of the problems that occur in long-running systems involve the way that the system uses memory. We have developed a framework for extracting and building a model of the heap from a running Java system. Such a model is only useful if the programmer can extract from it the information they need to understand, find, and eventually fix memory-related problems in their system. This paper describes...
We have investigated a technique for recognising faces invariant of facial expressions. We apply multi-linear tensor algebra, which subsumes linear algebra, to analyse and recognise 3D face surfaces. This potent framework possesses a remarkable ability to deal with the shortcomings of principle component analysis in less constrained situations. A set of vector spaces can be used to represent the variation...
In a virtual sculpture project, we would like to sculpt in real-time very large 3D objects sampled in volume elements (voxels). The drawback of this kind of representation is the important number of voxels required to represent very large and detailed objects. Consequently, that entails important memory cost and computation time issues. In order to allow real-time performance, we propose in this paper...
