Shape-Aware Topological Representation for Pipeline Hyperbola Detection in GPR Data
Meiyan Kang, Shizuo Kaji, Sang-Yun Lee +3
Ground Penetrating Radar (GPR) is a widely used Non-Destructive Testing (NDT) technique for subsurface exploration, particularly in infrastructure inspection and maintenance. Howev…
Topological flow data analysis for transient flow patterns: a graph-based approach
Takashi Sakajo, Takeshi Matsumoto, Shizuo Kaji +2
We introduce a method of time series analysis for two-dimensional transient flow patterns based on Topological Flow Data Analysis (TFDA), a new approach to topological data analysi…
Topology-based Filtering of Graph Signals via Persistent Homology
Matias de Jong van Lier, Sebastián Elías Graiff Zurita, Shizuo Kaji
We study topology-based filtering of vertex-defined signals on graphs and their two-dimensional analogues. Unlike graph-spectral filters, the proposed approach distinguishes featur…
