We propose a perceptually based system for pattern retrieval and matching. The central idea is that similarity judgment has to be modeled along perceptual dimensions. Hence, we detect basic visual categories that people use in their judgment of similarity, and design a computational model that accepts patterns as input and, depending on the query, produces(More)
This paper describes a practical synthetic visual environment for use in CAD and teleoperation. Instead of using expensive head mounted display systems, we use a standard display and compute smooth shaded images using an AT&T Pixel Machine. The interface uses a VPL DataGlove [9] to track the hand, bringing the synthetic world into the same space as the(More)
We determine the basic categories and the hierarchy of rules used by humans in judging similarity and matching of color patterns. The categories are: (1) overall color; (2) directionality and orientation; (3) regularity and placement; (4) color purity; (5) complexity and heaviness. These categories form the pattern vocabulary which is governed by the(More)

1. PANEL INTRODUCTION Following the great standards set by the panels in the workshops held in the last two years [1,2], we have this year again a distinguished panel to discuss and debate the directions and frameworks for telepresence. Some of the questions brought up in the last two years continue to be on the top of our minds: Why is telepresence not as(More)
