Abstract

Creating animated human characters has been a goal of computer graphics for decades. Due to improvements in capture technology, realistic and highly detailed human motion data is now widely available. I will discuss how to create and preprocess large motion databases to control animated characters through intuitive user interfaces. The motion is preprocessed to add variety and flexibility by creating connecting transitions

where good matches in poses, velocities, and contact state of the character exist. The motion is then clustered into groups for efficient searching and for presentation in the interfaces. Three user interface techniques, choice-based, sketch-based, and performance-based interfaces, will be discussed.

I will also discuss how to enhance the flexibility and reusability of motion-captured data through hierarchical displacement mapping and multiresolution analysis.

Speaker Biography

Jehee Lee received a BS degree in computer science from the Korea Institute of Technology in 1993 and a Masters degree and a Ph.D. in computer science from the Korea Advanced Institute of Science and Technology (KAIST) in 1995 and 2000, respectively. He is currently a postdoctoral fellow of the Robotics Institute at Carnegie Mellon University. His primary research interests are computer graphics, interactive control of 3D characters, motion editing and retargeting, multiresolution analysis/synthesis, and motion signal processing.
