Prof. H. Samet of the University of Maryland will speak on ``An Overview of Quadtree Research.'' TIME: 10:30 AM (Please Note) ROOM: MC 5158 ABSTRACT Region representation is an important issue in image processing, cartography, and computer graphics. A wide number of representations is currently in use. Recent- ly, there has been much interest in a hierarchical data structure termed the quadtree. It is compact and depending on the nature of the region saves space as well as time and also facilitates operations such as search. In this talk we give a brief overview of the quadtree data structure and related research results. October 11, 1983
