A new contour extraction method is described in this paper. It is based on organization of the image data using perceptual grouping rules, and is therefore largely domain independent. The first step is to form an intermediate line segment representation of the contours by grouping edge points in parallel and at different resolutions. The main feature of the line segment extraction process is the identification, by perceptual criteria, of weak but significant edge points for participation in the grouping process. In the second stage the line segments are grouped into contours, again on the basis of perceptual criteria. This grouping stage is carried out hierarchically using a pyramid structure. In both cases, the use of perceptual grouping allows the filtering of noisy edges and line segments regardless of their strength.
Tensor product surfaces are now widely used in application areas such as industrial design and computer animation and thus the quest for more effective design methods continues. Although several methods exist for appl...

Many applications would benefit from graphical simulation and emerging virtual environment (VE) technologies, and for many of these cases, the VE system must be able to display accurate models of human figures. The author surveys major modeling techniques for representing and simulating synthetic humans, or virtual actors, and discusses the relative importance of these simulation and modeling techniques for various VE applications.< >

In this article we explore the role computing can play in an electromagnetics class. Our aim is not to provide answers, but to open a discussion on several topics related to the use of the computer as a learning aid. We provide some examples of what we have done in an introductory electricity and magnetism class using a program called SilverHammer that maps electric and magnetic fields for point charges. However, the point of this article is not to say that this is the only way computers should be used, but rather to point out that we really have only scratched the surface of a very versatile tool. Those who are presently working in this area are the pioneers, and will see the use of the computer go from these first applications to being an indispensable medium for learning. The computer may well let us create virtual scenarios that allow us to explore ideas and relationships with a heretofore unattained proficiency.
A technique is described for adding natural‐looking hair to standard rendering algorithms. Using an explicit hair model, in which each individual hair is represented by a three‐dimensional curve, the technique uses ...
