SCIA 2011wasthe 17thinthe biennialseriesofconferences,whichhas been organized in turn by the Scandinavian countries Sweden, Finland, Denmark, and Norway since 1980. The event itself has always attracted participants and author contributions from outside the Scandinavian countries, making it an in- ternational conference. The conference included a full day of tutorials and five keynote talks pro- vided by world-renowned experts. The program covered high-quality scientific contributionswithin image analysis,segmentation,multiple view geometry,cat- egorization and classification, structure from motion and SLAM, medical and biomedical applications, 3D shape, and medical imaging. For the first time in the SCIA history, we used a two-stage reviewing system with the ten Program Committee members serving as Area Chairs, each responsible for about 15 pa- pers. The papers were carefully selected based on three reviews and a consol- idating report and acceptance/rejection recommendation from the responsible AreaChair.Among 140submissions74wereaccepted,leadingto anacceptance rate of 53%. SCIAhas a reputationofhavingafriendly environment,inadditiontohigh- quality scientific contributions. We focused on maintaining the reputation, by designing a technical and social program that we hope the participants found interestingandinspiringfornewresearchideasandnetworkextensions.Wealso hopethattherelaxedandniceatmosphereatYstadSaltsj¨obadalsocontributed. We thank the authors for submitting their valuable work to SCIA. This is of course of prime importance for the success of the event. However, the orga- nization of a conference also depends critically on a number of volunteers. We are sincerely grateful for the excellent work done by the reviewers and the Pro- gram Committee members, which ensured that SCIA maintained its reputation ofhighquality.Wethankthekeynoteandtutorialspeakersfortheirenlightening lectures.Andfinally,wethankthelocalOrganizingCommitteeandalltheother volunteers that helped us in organizing SCIA 2011. WehopethatallparticipantshadajoyfulstayinYstad,andthatSCIA2011 met its expectations.
