Motivation
[Winkler et al, 2010]
Problem statement
is an isometry
Challenges
Poses do not match perfectly• Focus on rigid areas• Focus on a compact area
State of the art
PCA based algorithms
[Chaouch et al, 2008]
[Aiger et al, 2008]
ICP based algorithms
Randomized algorithms
Global!
Require a good start solution!
Global!
Requires high overlapping (> 40%)!
The algorithm
Select a Region of Interest (ROI)
Register poses by aligning ROIs
ROI detection
0
MAX• Detect seeds ( )
• Max surface
• Region growing
[Meyer et al, 2002]
Registration
[Sorkine, 2007]
Results
26,907 TOT vertices1,092 ROI vertices174ms
7,207 TOT vertices965 ROI vertices59ms
7,207 TOT vertices544 ROI vertices56ms
Multiple poses
• All vs All
• Chain
• All vs 1
Conclusions
• Based on Gaussian Curvature
• Easy to implement
• Multiple poses
