“We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input.”
I was under the impression these experiments required a pre mapped room with EM readings. I don’t think they can watch you like if it was an X-ray but I’d believe it if they could track blobs of moving mass.
