"... By Hyun Joon Shin ∗ and Jehee Lee Human motion is difficult to create and manipulate because of the high dimensionality and spatiotemporal nature of human motion data. Recently, the use of large collections of captured motion data has added increased realism in character animation. In order to make ..."

Computer Puppetry: An Importance-Based Approach Hyun Joon Shin Jehee Lee Michael Gleicher Sung Yong Shin
, 2001
"... Computer puppetry maps the movements of a performer to an animated character in real time. In this paper, we provide a comprehensive solution to the problem of transferring the observations of the motion capture sensors to an animated character whose size and proportion may be different than the per ..."

Motion Integration and Segmentation Lee Stone, NASA ARC IHH
"... Over the last two decades much has been learned about human ability to detect and discriminate information within local patches of image motion. Indeed, a model consisting of spatio-temporal motion energy detectors is an excellent descriptor of both human low-level motion perception and visual proce ..."

W.: Behavioral dynamics of steering, obstacle avoidance, and route selection
- Journal of Experimental Psycholology: Human Perception Performance
, 2003
"... The authors investigated the dynamics of steering and obstacle avoidance, with the aim of predicting routes through complex scenes. Participants walked in a virtual environment toward a goal (Experiment 1) and around an obstacle (Experiment 2) whose initial angle and distance varied. Goals and obsta ..."

, steering toward goals, avoiding obstacles, and adopting particular routes through the cluttered landscape? This basic problem has inspired a good deal of research on the optical information available to a moving observer and the visual perception of self-motion (Gibson, 1958/1998; Land, 1998; Lee, 1980
Learning Silhouette Features for Control of Human Motion
- ACM Trans. Graph
, 2004
"... features that are computed on the silhouette images [Viola and Jones 2001]. These features are computationally efficient and therefore suited to real-time applications. The best local features for estimating yaw and body configuration are selected from a very broad set of possible features based on ..."

The database is pre-processed into an augmented motion graph that extends the motion graph [Lee et al. 2002] to handle scaling in velocity and two interacting characters. The search for the pose
The Exhu-mation and Identlfleatlon of Lee Harvey Oswald
"... ABSTRACT: The investigations surrounding the assassination of President John F. Kennedy and the subsequent killing of Lee Harvey Oswald resulted in many theories concerning what really happened in November 1963. One theory postulated the substitution of a Russian agent for Oswald; another that his ..."

BEHAVIORAL AND COGNITIVE NEUROSCIENCE REVIEWS Blake, Lee / VISUAL TEMPORAL STRUCTURE The Role of Temporal Structure in Human Vision
"... Gestalt psychologists identified several stimulus properties thought to underlie visual grouping and figure/ground segmen-tation, and among those properties was common fate: the ten-dency to group together individual objects that move together in the same direction at the same speed. Recent years ha ..."

have witnessed an upsurge of interest in visual grouping based on other time-dependent sources of visual information, including synchro-nized changes in luminance, in motion direction, and in figure/ ground relations. These various sources of temporal grouping information can be subsumed under
An Evaluation of a Cost Metric for Selecting Transitions between Motion Segments
, 2003
"... Designing a rich repertoire of behaviors for virtual humans is an important problem for virtual environments and computer games. One approach to designing such a repertoire is to collect motion capture data and pre-process it to form a structure that can be walked in various orders to re-sequence ..."
