Here are some implementations of the expirements done in the "Persistence-based Structural Recognition" paper by Chunyuan Li, Maks Ovsjanikov and Frederic Chazal.
Execute pip install -r requirements.txt to install dependencies. Then unzip Data_Hand.zip in a Data_Hand folder and Data_Perso.zip in a Data_Perso folder.
The command to execute: python3 exp1.py
This computes the 0-persistence diagrams of the HKS function at different times and plots them:
The command to execute: python3 exp2.py
This computes the confusion matrix:
