Transcript of Consistent Segmentation of 3D Models Aleksey Golovinskiy Thomas Funkhouser Princeton University.
Consistent Segmentation
Consistent Segmentation:• More useful• Better segmentations
Individual Segmentations
Consistent Segmentations
• Fuzzy clustering and min cuts• Shape Diameter Function• K-means
[Katz and Tal 2003]
[Shlafman et al. 2002]
[Shapira et al. 2008]

Shuffler [Kraevoy 06] • Oversegment• Combine segmentsLimitations• Only pairs• No outliers
Single Mesh Segmentation
• Segmentation error encourages– Small perimeter– Concave boundaries– Similar areas
• Greedy search procedure– Aggregate segments
Segmentation Error
• wconcave encourages concave boundaries
