Edición de la obra Robot vision

On behalf of the organizerswe would like to welcome all participants to the “Robot Vision 2001” workshop. Our objective has been to bring together - searchersinrobotvision,andtopromoteinteractionanddebate. Participants oftheworkshopcomefromEurope,US,theMiddleEast,theFarEast,andof coursefromNewZealand. Fifty-twopapersweresubmittedtotheworkshop,andeachpaperwasth- oughlyreviewedbyatleastthreereviewers. Seventeenpaperswereselectedfor oral presentation, and seventeen papers were selected for poster presentation. There were no invited technical papers, to give all participants the sense of equalopportunity. Thetechnicalscopeoftheworkshopisverywide,andincludespresentations onmotionanalysis,3Dmeasurements,calibration,navigation,objectrecog- tion,andmore. Thescheduleoftheworkshopwasthereforepreparedtoallow, inadditiontothetechnicalpresentation,ampletimefordiscussionsandint- action.^ Wehopethatinteractionamongresearchersofsuchdi?erentareas,yet allpartofrobotvision,willresultinbetterunderstandingandresearchofthe robotvisionarea.
