Advances in image and video technology

These proceedings are a manifestation of the excellent scienti? c contributions presented at the Second IEEE Paci? c Rim Symposium on Video and Image Technology (PSIVT 2007), held in Santiago, Chile, during December 17–19, 2007. The symposium provided a forum for presenting and exploring the l- est research and developments in image and video technology. Discussing the possibilities and directions in these ? elds settled a place where both academic research and industrial activities were presented for mutual bene? t. The aim of the symposium was to promote and disseminate ongoing research on multi- dia hardware and image sensor technologies, graphics and visualization, image analysis, multiple view imaging and processing, computer vision applications, image and video coding, and multimedia processing. The volume is a realization of the ongoing success of the Paci? c Rim Symposium on Video and Image Te- nology for which the ? rst issue (PSIVT 2006) was last year in Hsinchu, Taiwan, Republic of China. PSIVT 2007 provides evidence of the growing stature of the Paci? c Rim s- enti? c community in video and image technology andof their impact worldwide. The symposium received contributions from 31 countries, registering a total of 155 papers, out of which 75 were accepted for publication in these proce- ings, which is equivalent to an acceptance rate of 48. 4%. The review process was carried out in seven di? erent themes, each composed of theme Co-chairs and a ProgramCommittee composed of internationally recognized scientists, all experts in their respective theme. Each paper was peer-reviewed by two to ? ve reviewers.
