We received quite a high number of paper submissions: 382 in total for both confer- ences. We had contributions from more than 50 countries in all five continents. This confirms the success and global dimension of these jointly organized conferences. After a rigorous double-blind evaluation method, a total of 78 submissions were accepted as full papers. From those, 18 got selected for inclusion in this book. To ensure the scien- tific quality of the contributions, these were selected from papers that were evaluated with the highest scores by the VISIGRAPP Program Committee members and then they were extended and revised by the authors. Special thanks go to all contributors and refe- rees, without whom this book would not have been possible. VISIGRAPP 2007 included four invited keynote lectures, presented by internation- ally recognized researchers. The presentations represented an important contribution to increasing the overall quality of the conference. We would like to express our ap- preciation to all invited keynote speakers, in alphabetical order: Jake K. Aggarwal (The University of Texas at Austin/USA), André Gagalowicz (INRIA/France), Wolf- gang Heidrich (University of British Columbia/Canada), Mel Slater (Universitat Politècnica de Catalunya/Spain). We wish to thank all those who supported and helped to organize the conference. First and foremost we would like to acknowledge the collaboration from Eurographics and CVC - Computer Vision Center. Moreover, on behalf of the conference Organiz- ing Committee, we would like to thank the authors, whose work mostly contributed to a very successful conference, and to the members of the Program Committee, whose expertise and diligence were instrumental to the quality of the final contributions. We also wish to thank all the members of the Organizing Committee whose work and commitment were invaluable. Last but not least, we would like to thank Springer for their collaboration in getting this book to print.
