Gerhard Sagerer, University Bielefeld Klaus Tempfli, ITC Enschede Roy Welch, University of Georgia The workshop wants to bring together specialists in image analysis, digital photogrammetry, GIS and cartography to discuss the current state of automatic procedures for acquiring object information from images and maps. It will deal only with topograhic objects, especially in urban regions, and will focus on 3-D approaches. The goal is to find common object models and analysis strategies with emphasis on the integration of multiple information and knowledge sources. The topics will refer to basic research or advanced applications of digital photogrammetry and computer vision for geo-database generation and update. As such we solicit papers in the following areas: (1) 3D object recognition and extraction (2) 3D object models in image analysis and GIS (3) Integration of multiple cues and knowledge sources: o GIS supported object recognition o Use of DSMs and orthoimages for object extraction (4) 3D GIS database generation and update, with emphasis on urban applications (5) Encapsulation, representation, and use of knowledge (6) Use of image analysis for extracting height information for 2D geo-databases We will prefer unpublished work, even if it is not complete yet. The workshop will consist of invited, oral and possibly poster presentations. Approximately 30 minutes will be allocated for paper presentation. The Workshop directly proceeds the Photogrammetric Week '97 Conference and can be favourably combined with it. Paper submissions for review should be approximately 8 pages long including figures, tables and references, single spaced using a 12 point font. Alternatively 1000-word extended abstracts may be submitted for review and should convey the technical approach and results of the research. Authors should give their full address including phone, fax and e-mail. In case of multiple authors, indicate the name of one author for further contacts. If you wish, you can indicate one of the three WGs for which your paper is intended. Please send three (3) copies of FULL PAPERS or EXTENDED ABSTRACTS (1000 words) by 15 April, 1997 to: Dr.-Ing. Eberhard Guelch Institute of Photogrammetry University Bonn Nussallee 15 D-53115 Bonn Germany e-mail: ebs@ipb.uni-bonn.de Phone: +49-228-732721 FAX: +49-228-732712 Timetable: 15 April, 1997 Deadline for extended abstracts 15 May, 1997 Notification of authors 15 July, 1997 Camera ready manuscript are due 17-19 September, 1997 Workshop For latest information on the Workshop visit the Web-Page: http://wwwradig.informatik.tu-muenchen.de/ISPRS/WG-III4-IV2-Workshop.html Information on the WGs can be found in the following WWW addresses: WG III/4: http://wwwradig.informatik.tu-muenchen.de/ISPRS/wgIII.4.html WG IV/2: http://www.ifp.uni-stuttgart.de/comm4/wgIV2.html IC WG IV/III.2: http://www.ifp.uni-stuttgart.de/comm4/wg4_32.html
