This congressis anopportunity for the exchangeanddiffusion ofknowledge, as well as for the promotion of collaboration among different research groups from Latin America, Spain, Portugal and the rest of the world. Like previous editions, this event attracted contributions from many coun- tries.ThepaperspresentedherecamefromArgentina,Austria,Belgium,Brazil, Chile, Colombia, Costa Rica, Cuba, Czech Republic, Guadeloupe, India, Iran, Italy,Malaysia,Mexico,TheNetherlands,NewZealand,Peru,Portugal,Russian Federation, Slovenia, Spain, Thailand, Tunisia, USA and Uruguay. The papers containedin this volume were selected by the ProgramCommit- tee,consistingofLuisAlvarezLeon,LuisGomezDeniz,JulioJacobo,andMarta Mejail. Each submitted paper was carefully reviewed by about three reviewers in a double-blind peer-review process. Six distinguished invited speakers gave two tutorials and four keynotes.One ofthetutorialsaddressedthesubjectofhumanactivityrecognitionwith2Dand 3D cameras and was given by Zicheng Liu, from Microsoft Research; the other tutorialtreatedthesubjectofMarkovrandomfieldswithemphasisonrestricted Boltzmann machines, and was given by Christian Igel from the University of Copenhagen. A keynote on pattern recognition in transportation was presented by Jos´e Antonio Rodriguez-Serrano, Research Scientist at the Xerox Research Centre Europe(XRCE) Group. Another keynote on optimal anti-Bayesian statistical pattern recognition was given by John Oommen from the School of Computer ScienceatCarletonUniversity,Ottawa(Canada).“Robot,passmethescissors”! wasakeynotethataddressedthe problemofrobotsassistanceinsurgery,itwas presented by Juan P. Wachs from Purdue University. A keynote on multi-class support vector machines was presented by Christian Igel from the University of Copenhagen. Akeynoteonsmoothsigneddistancesurfacereconstructionandapplications was presented by Gabriel Taubin from Brown University. Toenhancetheimportanceofthiscongress,extendedversionsofselectedpa- pers will be included in the Special Issue onComputer Vision Applying Pattern Recognition Techniques (Pattern Recognition), in the Special Issue on Robust Recognition Methods for Multimodal Interaction (Pattern Recognition Letters), intheSpecialIssueonReal-TimeImageandVideoProcessingforPatternRecog- nition Systems and Applications (Journal of Real-Time Image Processing) and in the IPOL Publications of Algorithms. VI Preface Wewishtothankallthosewhosubmittedpapersforconsiderationandallthe Program Committee members for their excellent work.
