Persistence Diagram for Structural Recognition

Experiments

3D Shape Retrieval

1. Go to folder 'PD_shape/scripts/experiments_nonrigid/'. Please donwload the 3D mesh shape datasets here

2. Run ‘compute_LB_eigen.m’ to obtain the eigenvalues and eigenvector for meshes

3. Find all PD related code in 'PD_shape/scripts/'

Hand Gesture Classification

1. Data: Please unzip the data in 'PD_shape/Data.zip'

2. Find all PD related code in 'PD_shape/'
