Bobick Artificial Intelligence Center SRI International A technique to build reliable scene descriptions by evaluating the temporal stability of detected objects is presented. Although current scene analysis techniques usually analyze individual images correctly, they occasionally make serious mistakes that could endanger an autonomous vehicle that is depending upon them for navigational information. Our approach is designed to avoid these ugly mistakes and to increase the competence of the sensing system by tracking objects from image to image and evaluating the stability of their descriptions over time. Since the information available about an object can change significantly over time, we introduce the idea of a representation space, which is a lattice of representations progressing from crude blob descriptions to complete semantic models, such as bush, rock, and tree. One of these representations is associated with an object only after the object has been described multiple times in the representation and the parameters of the representation are stable. We define stability in a statistical sense enhanced by a set of explanations describing valid reasons for deviations from expected measurements. These explanations may draw upon many types of knowledge, including the physics of the sensor, the performance of the segmentation procedure, and the reliability of the matching technique. To illustrate the power of these ideas we have implemented a system, which we call TraX, that constructs and refines models of outdoor objects detected in sequences of range data. This work is a joint project with Bob Bolles. ------------------------------ Date: 4 Nov 88 12:31:25 GMT From: prlb2!ronse@uunet.UU.NET (Christian Ronse) Subject: convexity bibliography update Organization: Philips Research Laboratory, Brussels Keywords: 370 entries! In February 1987 I publicised on the net a convexity bibliography with over 250 entries. Many people asked me a copy of it. It has since been updated and contains now 370 entries. It will appear in IEEE Trans. PAMI in early 1989, probably in March. You can again ask me a copy of it, provided that you can't wait until March or you don't have PAMI in your library.

Manning) Subject: PIX IPS vision bulletin board 508-441-2118 Keywords: software Organization: 3M Company - Software and Electronics Resource Center (SERC); St. Paul, MN Paragon Imaging has set up a bulletin board for vision topics and also to promote their IPS (Image Processing Software) package. All the stuff I've seen so far has been in FORTRAN, but other source code may appear soon. It is a fairly unsophisticated system, but it may prove useful. Paragon advertized this at Electronic Imaging in Boston last month. Arthur T. Manning Phone: 612-733-4401 3M Center 518-1 FAX: 612-736-3122 St. Paul MN 55144-1000 U.S.A.
