Untangling Dense Crowds with mmWave Radar: From Crowd Semantics to Individual Spatial Behaviors
Aaditya Prakash Kattekola, Anurag Pallaprolu, Yasamin Mostofi
In this paper, we present a novel framework for recovering individual footprints and pedestrian spatial behaviors in dense crowds. This is a highly challenging problem, as pedestri…
Fast and Robust Stationary Crowd Counting with Commodity WiFi
Mert Torun, Alireza Parsay, Yasamin Mostofi
This paper introduces a novel method for estimating the size of seated crowds with commodity WiFi signals, by leveraging natural body fidgeting behaviors as a passive sensing cue.…
Embracing Diffraction: A Paradigm Shift in Wireless Sensing and Communication
Anurag Pallaprolu, Winston Hurst, Yasamin Mostofi
Wireless signals are integral to modern society, enabling both communication and increasingly, environmental sensing. While various propagation models exist, ranging from empirical…
mmFlux: Crowd Flow Analytics with Commodity mmWave MIMO Radar
Anurag Pallaprolu, Winston Hurst, Yasamin Mostofi
In this paper, we present mmFlux: a novel framework for extracting underlying crowd motion patterns and inferring crowd semantics using mmWave radar. First, our proposed signal pro…
Gait Disorder Assessment Based on a Large-Scale Clinical Trial: WiFi vs. Video vs. Doctor's Visual Inspection
Alireza Parsay, Mert Torun, Philip R. Delio +1
Neurological gait disorders affect a large population, significantly reducing life quality. This paper brings a foundational understanding to the potentials of emerging sensing mod…
mmSnap: Bayesian One-Shot Fusion in a Self-Calibrated mmWave Radar Network
Anirban Banik, Lalitha Giridhar, Aaditya Prakash Kattekola +4
We present mmSnap, a collaborative RF sensing framework using multiple radar nodes, and demonstrate its feasibility and efficacy using commercially available mmWave MIMO radars. Co…
