Exploring Spatial-Temporal Representation via Star Graph for mmWave Radar-based Human Activity Recognition

Senhao Gao, Junqing Zhang, Luoyu Mei +2

Human activity recognition (HAR) requires extracting accurate spatial-temporal features with human movements. A mmWave radar point cloud-based HAR system suffers from sparsity and…
