Robotics Graduate Student Seminar
Detecting Symmetric Objects in 3D Pointclouds
PhD Candidate, Computer Science
Advisors: Prof. Yiannis Aloimonos and Dr. Cornelia Fermuller
Symmetry is a common property shared by the majority of man-made objects. In this talk I will present a novel bottom-up approach or detecting symmetric objects and recovering their symmetries from 3D pointclouds of natural scenes. Candidate rotational and reflectional symmetries are detected by fitting symmetry axes/planes to the geometry of the smooth surfaces extracted from the scene. Individual symmetries are used as constraints for the foreground segmentation problem that uses symmetry as a global grouping principle. Evaluation on a challenging dataset shows that our approach can reliably segment objects from incomplete reconstructions of highly cluttered scenes, outperforming state-of-the-art bottom-up methods by a wide margin.
About the Robotics Graduate Student Seminars
The Robotics Graduate Student Seminars at the University of Maryland College Park are a student-run series of talks given by current graduate students.
The purpose of these talks is to:
- Encourage interaction between Robotics students from different subfields;
- Provide an opportunity for Robotics students to be aware of and possibly get involved in the research their peers are conducting;
- Provide an opportunity for Robotics students to receive feedback on their current research;
- Provide speaking opportunities for Robotics students.
