ISPRS Intercommission Workshop FROM PIXELS TO SEQUENCES - SENSORS, ALGORITHMS AND SYSTEMS - March 22 - 24, 1995 Zurich, Switzerland SECOND ANNOUNCEMENT AND PRELIMINARY PROGRAM Organising ISPRS Working Groups * WG I/3 - Optical Digital Imaging Systems * WG V/2 - Close-Range Imaging Systems and their Performance * IC WG V/III - Image Sequence Analysis Cooperating Organisations * International Society for Photogrammetry and Remote Sensing (ISPRS) * Swiss Society for Photogrammetry, Image Processing and Remote Sensing * Institute of Geodesy and Photogrammetry, ETH Zurich Invitation During the last years, opto-electronic sensors have gained importance in areas such as photogrammetry, remote sensing, machine, robot and computer vision. They provide an effective way of fast image acquisition and the potential of automated image analysis. Digital images, in combination with on-line data evaluation, are a valuable tool for automating quality control and are of particular importance for recording kinematic processes, promising to revolutionize a wide range of measurement tasks. This workshop intends to deal with basic tools ranging from object illumination, image recording, A/D conversion to image processing and image evaluation employed in digital photogrammetry, emphasizing on precision, reliability, robustness, speed, technical advancements and new applications. Keynote speakers, presented papers and discussions will present the state-of-the-art and future developments. During the three days of the workshop, researchers and practitioners from digital photogrammetry, digital image processing, machine vision and related fields will have the opportunity to put in perspective the interrelationships of all involved disciplines, thus maximizing mutual gains. You are cordially invited to participate and contribute to its success. Workshop site The workshop will be held at ETH-Hoenggerberg, a campus of the Swiss Federal Institute of Technology (ETH) Zurich, which is conveniently located close to downtown Zurich in a restful and delightful natural environment. TECHNICAL PROGRAM Eighty abstracts were submitted and evaluated by the chairmen of the three ISPRS Working Groups organising the workshop. This high number of papers and the general interest that was expressed makes us confident that the issues to be dealt with in this workshop are relevant to a great number of experts and users in the related fields. Sixty selected papers from 14 different countries will be presented in 11 Technical and 2 Poster Sessions (35 and 25 papers respectively). Most technical sessions have only 3 papers, thus allowing plenty of time for intensive discussions and preserving the workshop character of the meeting. In the poster sessions, authors will have the possibility for a short presentation of their paper, before the interactive discussion at the posters. The Opening Session will feature a keynote speech by an expert in the field of electronic imaging, Dr. Peter Seitz, Paul Scherrer Institute Zurich (former RCA Lab.), with title "From pixels to answers - recent developments and trends in electronic imaging". The proceedings of the workshop will be published in the series of the International Archives of Photogrammetry and Remote Sensing (IAPRS, Vol. 30, Part 5W1) and will be available on-site. The technical language of the meeting will be English.
