This volume presents the proceedings of the 10th International Conference on Computer Analysis of Images and Patterns (CAIP 2003). This conference - ries started about 18 years ago in Berlin. Initially, the conference served as a forum for meetings between scientists from Western- and Eastern-bloc co- tries. Nowadays, the conference attracts participants from all over the world. The conference gives equal weight to posters and oral presentations, and the selected presentation mode is based on the most appropriate communication medium. The programme follows a single-track format, rather than parallel s- sions. Non-overlapping oral and poster sessions ensure that all attendees have the opportunity to interact personally with presenters. As for the numbers, we received a total of 160 submissions. All papers were reviewed by two to three members of the Programme Committee. The final - lection was carried out by the Conference Chairs. Out of the 160 papers, 42 were selected for oral presentation and 52 as posters. At this point, we wish to thank the Programme Committee and additional referees for their timely and high-quality reviews. The paper submission and review procedure was carried out electronically. We thank Marcin Morg´ os from Scalar–IT Solutions for p- viding us with the Web-based participant registration system. We also thank the invited speakers Nicholas Ayache, John Daugman, and Dariu Gavrila, for kindly accepting our invitation.
