Presumably simple: monitoring crowds using WiFi

by Cristian Chilipirea, Andreea-Cristina Petre, Ciprian Dobre Sept. 12, 2017 via

In this paper, we investigate various techniques for cleaning up sets of raw detections to sets that can subsequently be used for crowd analytics. To this end, we introduce two different quality metrics to measure the effects of applying various data filters.
