1. Key-posture Extraction Out of Human Motion Data by Curve Simplification IEEE Engineering in Medicine and Biology Society (EMBC) 2001 Speaker: Alvin Date: 4/18/2005

2. 2 Alvin/GAME Lab./CSIE/NDHU Introduction Useful for storage of motion data. A kind of animation compression. Treat the motion data as trajectory curve in high dimensions. Use curve simplification technique.

4. 4 Alvin/GAME Lab./CSIE/NDHU Results

5. 5 Alvin/GAME Lab./CSIE/NDHU Results

6. 6 Alvin/GAME Lab./CSIE/NDHU Future Works Consider the weights of joints. Try another curve simplification technique. Different error measurement. Consider the entire content of the motion. Adopt this scheme to my segmentation.
