Foreword: We warmly welcome you to SIGMAP 2007 - the International Conference on Signal Processing and Multimedia Applications, which is held, this year, in Spain. This conference reflects a continuing effort to increase the dissemination of recent research among professionals who work on the fields of Signal Processing and Multimedia, especially for telecommunications. SIGMAP is integrated as one of the modules of the ICETE joint conference. The major goal of ICETE is to bring together researchers, engineers and practitioners interested in information and communication technologies, including e-business, wireless networks and information systems, security and cryptography, signal processing and multimedia applications. These are the main knowledge areas that define the four component conferences, namely: ICE-B, WINSYS, SECRYPT and SIGMAP, which together form the ICETE joint conference. In the program for this joint conference, we have included keynote lectures, tutorials, papers, and posters to present the widest possible view on these technical areas. With these tracks, we expect to appeal to a global audience of the engineers, scientists, business practitioners and policy experts, interested in the research topics of ICETE. All tracks focus on research related to real world applications and rely on contributions not only from the Academia but also from the industry, with different solutions for end-user applications and enabling technologies, in a diversity of communication environments. The proceedings demonstrate a number of new and innovative solutions for e-business and telecommunication, and demonstrate the vitality of these research areas. ICETE has received 418 papers in total, with contributions from more than 60 different countries, from all continents, which really shows the success and global dimension of ICETE 2007. To evaluate each submission, a double blind paper evaluation method was used: each paper was reviewed by at least two experts from the International Program Committee, in a double-blind review process, and most papers had 3 reviews or more. In the end, 175 papers were selected for oral presentation and publication, corresponding to a 41% acceptance ratio. Of these only 62 were accepted as full papers (15% of submissions) and 113 as short papers. Additionally, 99 papers were accepted for poster presentation. These acceptance ratios demonstrate that ICETE 2007 strives to achieve a high quality standard which we will keep and enhance in order to ensure the success of next year conference, to be held in Barcelona/Spain. Furthermore, a short list of about thirty papers will be selected to appear in a book that will be published by Springer. We would like to emphasize that ICETE 2007 includes several outstanding keynote lectures in areas which are very relevant, nowadays. These talks are presented by distinguished researchers who are internationally renowned experts in all ICETE areas, and contribute to heighten the overall quality of the Conference. A successful conference involves more than paper presentations; it is also a meeting place, where ideas about new research projects and other ventures are discussed and debated. Therefore, a social event including a conference diner was organized for the evening of July 29 in order to promote this kind of social networking. We would like to express our thanks, first of all, to the authors of the technical papers presented at the conference, whose work made possible to put together a high quality program. Next, we would like to thank all the members of the program committee and reviewers, who helped us with their expertise, dedication and time. We would also like to thank the invited speakers for their invaluable contribution, sharing their vision and knowledge. Naturally, a word of appreciation for the work of the secretariat and all other members of the organization, whose diligence in dealing with all organizational issues were essential and required a collaborative effort of a dedicated and highly capable team. We hope that you will find these proceedings interesting and a helpful reference in the future for all those who need to address the areas of e-business and telecommunications. (More)
