The synthesis of motion capture data

Author : Tomáš SakoSupervisor : 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

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
