Abstract: A triangulated network of mobile units is modelled by means of a graph transformation system in which graph nodes are labelled with geometric coordinates and edges are la...
The distance between two graphs is usually defined by means of the size of a largest common subgraph. This common subgraph may be an induced subgraph, obtained by removing nodes, ...
The aim of this paper is to propose tools for statistical analysis of shape families using morphological operators. Given a series of shape families (or shape categories), the appr...
This paper presents user interface technology for mobile outdoor augmented reality systems, and a set of new techniques we have named construction at a distance for the capture an...
We present a modi cation of the well-known snakes algorithm for extracting contours in noisy images. Our modi cation addresses the issues of selection of the control points on an ...
