Device-Free Localization Using Privacy-Preserving Infrared Signatures Acquired from Thermopiles and Machine Learning

2021 - IEEE Access

This paper used low resolution (8 by 8 pixels) thermopiles to localise a subject. The subject does not require a device on their person, and can be positioned with 10-20 cm median accuracy. The system was tested upon a range of subjects in several environments without significant performance deterioration.
