Thisvolumecollectsthepapersacceptedforpresentationatthe7thInternational Conferenceon Advanced Conceptsfor IntelligentVision Systems (ACIVS 2005). TheACIVS conference was established in 1999 in Baden-Baden (Germany) as part of a large multiconference.ACIVS has maintained the tradition of its ?rst edition of having 25-minute oral talks in a single track event, even though the number of participants has been steadily growing every year. The conference currently attracts computer scientists from more than 20 countries, mostly from Europe, Australia and Japan, but also from USA, Asia and the Middle East. ThoughACIVS is a conference on all areas in image processing, one of its major domains is image and video compression. A third of the selected papers dealt with compression, motion estimation, moving object detection and other video applications. This year, topics related to clustering, pattern recognition and biometrics constituted another third of the conference. The last third was more related to the fundamentals of image processing, namely noise reduction, ?ltering,restorationandimagesegmentation.We wouldliketothankthe invited speakers Fernando Pereira, Marc Op de Beeck and Rafael Molina for enhancing the technical program with their presentations.
