The synthesis of motion capture data

1
The synthesis of motion capture data

• Author Tomáš Sako
• Supervisor RNDr. Stanislav Stanek

2
The submission of diploma thesis

• investigate the methods of the synthesis of
  motion capture data
• Result semi-interactive system
• Input captured motion data
• Output its composition
• Product mostly realistic motion

3
Benefit

• the creation of semi-interactive system for
  motion synthesis
• the implementation of Registration curves
  algorithm
• the comparison of simple and dual quaternions
  efficiency

Overview

• Motion synthesis (blending) methods
• manual, semi-automatic, automatic
• Registration curves by Lucas Kovar and Michael
  Gleicher
• features automatic, flexible, effective, quick,
  used in common blending operations
• advantage dynamic programming and other
  standards involved

Registration curves (1)

• Timewarp curve
• Coordinate-alignment curve
• Constraint matches
• Literature Kovar L., Gleicher M., Flexible

Experiments Verification

• efficiency tests - realistic output?
• flexibility tests - possible input
• speed tests miliseconds
• global comparison of algorithm with simple and
  dual quaternions
• conclusion
