A topology-based descriptor for 3D point cloud modeling: Theory and experiments

作者：

Highlights：

• STPP is a global shape descriptor for 3D point cloud data.

• It encodes a topological signature based on the pairing of homology generators.

• STPP can be computed quickly and efficiently, and uses a single tuning parameter.
