ISPRS Commission V Symposium 1994 March 1-4, 1994, Me~bourne, Austra//a The 1994 Intercongress Symposium of ISPRS Commission V "Close-Range Techniques and Machine Vision" was held in the World Congress Centre, Melbourne, Australia, March 1-4, 1994, combined with the 2nd Australian Photogrammetric Conference and simultaneously with the Pacific Ocean Remote Sensing Conference and the 7th Australian Remote Sensing Conference, in the week preceding the FIG Congress. 136 researchers and practitioners attended the Symposium. Commission V, which was traditionally mainly involved in architectural recording and non-topographic mapping, has opened a large variety of new applications during the last decade. This development can be attributed to the availability of solid-state imaging sensors and digital image processing techniques, which allow for the execution of measurement tasks thus far unsolvable. This trend was outlined in a keynote address by A. Gruen, who gave a status survey on 16 years of development in digital close-range photogrammetry, and was also clearly evident in the technical presentations, where industrial applications in the broader sense played a major role. Presentations on industrial applications concentrated on (but were not limited to) the car and aircraft industry, ship building and the generation of 3-D models of plants. Most of the systems and techniques used in production and quality control are based on solid-state sensors and automatic or semi-automatic data processing, while the extremely complex tasks in plant mapping are still being performed conventionally. Besides presentations on industrial applications and on the above-mentioned traditional fields of Commission V there were also sessions and presentations on biostereometrics, CAD/ CAM integration, robotics, progress in algorithms and knowledge-based vision. In addition, it seems that fields which were considered somewhat exotic in the past are becoming mainstream issues for Commission V. On the hardware side, CCD sensors currently play a major role and a clear tendency towards high-resolution sensors
(with up to 20,000 x 20,000 pixels) can be recognized; with camcorders and high-resolution still video cameras, data acquisition has also become independent of the presence of a host computer. The Symposium was well organized by John Fryer, Mark Shortis and their staff. Social highlights were the conference dinner in the Great Hall of the National Gallery and the reception party in the exhibition hall with an unparalleled amount of sushi. The Symposium proceedings contain 69 technical papers on 495 pages and are published by the APRSS (ISSN 0256-1840).

IEEE 2nd CAD-Based Vision Workshop February 8-11, 1994, Champ~on, Pennsylvan/a, USA The 2nd CAD-Based Vision workshop was the successor to the "Future Directions in Automated CADBased Vision" workshop held in Hawaii in June 1991. With a dramatic change of climate, this second workshop took place at the Seven Springs ski resort in the mountains east of Pittsburgh. It was jointly organised by Avi Kak (Purdue University) and Katsushi Ikeuchi (Carnegie Mellon University, CMU). The goals were set to review progress since the first workshop and to provide a clear picture of future directions. Some 61 participants were attracted to the meeting, primarily from the USA (49), but also from Japan (5), Europe (5), Canada (1) and Australia (1). Nearly all of these participants were either authors or co-authors of one of the 34 reviewed papers accepted for publication. Far from being a passive listening affair, the informal workshop atmosphere and generous time allotted for each of the eight technical sessions resulted, almost without exception, in the content of each of the papers being energetically discussed, both during and after the presentations. This was highly profitable to all participants who, it is fair to say, left with the feeling that the workshop was time well invested. In addition to the technical
