Preface
10th International Conference on Discrete Geometry for Computer Imagery Discrete topology and geometry for image and object representation DGCIÕ2002 was the 10th in the series of international conferences on Discrete Geometry for Computer Imagery. It was organized by the LaBRI (Laboratoire Bordelais de Recherche en Informatique, Universite Bordeaux 1, France) and took place in Bordeaux from April 3 to April 5, 2002. The aim of the DGCI conferences is to gather researchers in discrete geometry and topology, discrete models, with applications in image analysis and image synthesis. Discrete geometry plays an expanding role in the fields of shape modelling, image synthesis, and image analysis. It deals with topological and geometric definitions of digitized objects or digitized images and provides both a theoretical and computational framework for computer imaging. The nine papers in this special issue were selected among the 35 presented at DGCIÕ2002. They represent the diversity of the thematics tackled by the DGCI community. The first three papers propose general topological models: combinatorial representation of non-manifold objects (De Floriani et al.), hierarchical structure for image representation (Brun and Kropatsch), curve definition in a regular discrete space (Th€ urmer). The fourth paper proposes discrete geometry algorithms: digital line and plane recognition (Buzer). Then two contributions study the classical dual problems of digitization (Couprie et al.) and polygonalization (Andres). The last three contributions illustrate the various applications of discrete topology and geometry: shape thinning (Gau and Kong), image synthesis (Hetroy and Attali), image segmentation (Damiand and Resch). We thank the chief editors and the reviewers, whose work was essential in making this special issue.
