Contactless Vital Sign Monitoring for Multiple People Using a Millimeter-wave MIMO Radar

Yuan Liu, Xuemei Fu, Ritesh Chandra Tewari, Xingze Wang, Andy W. H. Khong

ICASSP 2025accepted

Radar technology offers much appeal for contactless vital sign monitoring. While most radar-based approaches achieve reasonable performance for single-person scenarios, they suffer from inaccurate vital sign estimates for multiple individuals, especially when the subjects occupy the same range bin.…

A Graph Neural Network Based Approach for Fault Delineation in Seismic Data using Graph Total Variation and Multigraph

Patitapaban Palo, Aurobinda Routray, Ritesh Chandra Tewari

ICASSP 2024accepted

Interpreting seismic data involves finding out subsurface geologic information. In seismic data interpretation, one of the crucial steps is to delineate seismic faults. Natural gas and oil reservoirs are more likely to be present where seismic faults exist. In this paper, we develop a graph neural n…
