Reviews: Learning elementary structures for 3D shape generation and matching

Summary: This paper states an interesting and novel idea- that learned shape bases could outperform hand-crafted heuristic functions. On the flip side, though, the method and experimental setups make drawing clear conclusions difficult, diminishing the impact. Post-rebuttal: The authors gave convincing responses to questions about the atlasnet comparison and about the number of parameters. So the final review is increased from 6 to 7. Originality: -As stated above, the paper has an interesting and novel high-level key idea. Whether the proposed method is really learning shape bases rather than using heuristic bases is a matter of interpretation, though.
