Uncertainty-aware Efficient Subgraph Isomorphism using Graph Topology

no code implementations15 Sep 2022 Arpan Kusari, Wenbo Sun

Subgraph isomorphism or subgraph matching is generally considered as an NP-complete problem, made more complex in practical applications where the edge weights take real values and are subject to measurement noise and possible anomalies.

A Probabilistic Framework for Estimating the Risk of Pedestrian-Vehicle Conflicts at Intersections

no code implementations28 Jul 2022 Pei Li, Huizhong Guo, Shan Bao, Arpan Kusari

To evaluate pedestrian safety proactively, surrogate safety measures (SSMs) have been widely used in traffic conflict-based studies as they do not require historical crashes as inputs.

Graph-theoretical approach to robust 3D normal extraction of LiDAR data

1 code implementation23 May 2022 Arpan Kusari, Wenbo Sun

A major challenge in LiDAR data analysis arises from the irregular nature of LiDAR data that forces practitioners to either regularize the data using some form of gridding or utilize a triangular mesh such as triangulated irregular network (TIN).
