DGCI2002,thetenthinaseriesofinternationalconferencesonDiscreteG- metry for Computer Imagery, was held in Bordeaux, France April 3-5, 2002. The aim of the conference was to present recent advances in both theoretical aspectsandapplicationsofdiscretegeometry. ItwasorganizedbytheLabo- toryofComputerScienceofBordeaux(Bordeaux1University)andsponsored bytheInternationalAssociationforPatternRecognition(IAPR)andtheFrench NationalCenterofScienti?cResearch(CNRS). This DGCI conference con?rmed the increasing interest of the computer imagery community for discrete geometry, with 67 papers submitted from 23 countriesallaroundtheworld. Afterreviewing,35contributionswereaccepted fromwhich22wereselectedfororalpresentationand13forposterpresentation. These contributions focus mainly on the following topics: Models for Discrete Geometry, Topology, Combinatorial Image Analysis, Morphological Analysis, Segmentation,ShapeRepresentationandRecovery,andApplicationsofDiscrete GeometryinImageProcessingandComputerGraphics. Thisprogramwascompletedbyinvitedlecturesfromthreeinternationally known speakers: Alfred M.Bruckstein (Haifa Computer Science Dept, Israel), Gabor Herman (City University of New York, USA), and Walter Kropatsch (TechnicalUniversityofVienna,Austria).
