This volume contains the papers accepted for presentation atMIRAGE 2007. The Mirage conference is becoming recognized internationally, with pres- tations coming from 31 countries. South Korea proved to be the most active scientifically with a total of 73 submitted papers, far aboveChina (27 submitted papers), Taiwan (10) and India (9), which proves the strong domination of Asia in the development of this new technology. We received a total of 198 submissions. Reviewing was very selective as the Program Committee accepted only 42 oral presentations and 17 posters. We had to extend the conference period from two to three days, as the number of submissions was mutiplied by three compared to the previous conference, which proves that this conference attracts more and more researchers. All papers were reviewedby two to four members of the ProgramCommittee. The final selection was carried out by the Conference Chairs. We wish to thank the Program Committee and additional referees for their timely and high-quality reviews.We also thank the invited speakers Peter Eisert and Adrian Hilton for kindly accepting to present very interesting talks. Mirage 2007 was organized by inria Rocquencourt and took place at inria, Rocquencourt, close to Versailles Castle.
