The synthesis of motion capture data Author : Tomáš Sako Supervisor : RNDr. Stanislav Stanek

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 2

Benefit

• • •

the creation of semi-interactive system for motion synthesis the implementation of Registration curves algorithm the comparison of simple and dual quaternions efficiency 3

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 6

Registration curves (1) 1) Timewarp curve 2) Coordinate-alignment curve 3) Constraint matches Literature : Kovar L., Gleicher M., Flexible
