Traditionally, scientific fields have defined boundaries, and scientists work on research problems within those boundaries. However, from time to time those boundaries get shifted or blurred to evolve new fields. For instance, the original goal of computer vision was to understand a single image of a scene, by identifying objects, their structure, and spatial arrangements. This has been referred to as image understanding. Recently, computer vision has gradually been making the transition away from understanding single images to analyzing image sequences, or video understanding. Video...

MOVING THE YOUTH DEVELOPMENT MESSAGE: TURNING A VAGUE IDEA INTO A MORAL IMPERATIVE Peter L. Benson and Karen Pittman THE CONTAGION OF AN IDEA In the past fifteen years, countless programs, agencies, funding initiatives, profes sionals, and volunteers have embraced the term "youth development. " Linked more by shared passion than by formal membership or credentials, these people and places have contributed to a wave of energy and activity not unlike that of a social movement, with a multitude of people "on the ground" connecting to a set of ideas that give sustenance, support, and value to...

3D Face Processing: Modeling, Analysis and Synthesis introduces the frontiers of 3D face processing techniques. It reviews existing 3D face processing techniques, including techniques for 3D face geometry modeling; 3D face motion modeling; and 3D face motion tracking and animation. Then it discusses a unified framework for face modeling, analysis and synthesis. In this framework, the authors present new methods for modeling complex natural facial motion, as well as face appearance variations due to illumination and subtle motion. Then the authors apply the framework to face...
