An advanced global point signature for 3D shape recognition and retrieval
We propose a novel 3D shape descriptor, called the Advanced Global Point Signature (AGPS), which is based on spectral analysis and is obtained by linear combination of some scaled eigenfunctions of the Laplace–Beltrami operator. Since it is built upon the concept of Global Point Signature, AGPS inhe...
