An advanced global point signature for 3D shape recognition and retrieval
作者：
Highlights：
•
• An Advanced Global Point Signature (AGPS) method for non-rigid 3D shape matching and retrieval is proposed.
• The method relies on the eigenpairs derived from the Laplace–Beltrami operator of the shape.
• AGPS is dramatically compact since only few eigenpairs were necessary to obtain an accurate shape description.
