Abstract

Objects in an environment affect electromagnetic waves. While this effect varies across frequencies, there exists a correlation between them, and a model with enough capacity can capture this correlation between the measurements in different frequencies. In this paper, we propose the Wi2Vi model for associating variations in the WiFi channel state information with video frames. The proposed Wi2Vi system can generate video frames entirely using CSI measurements. The produced video frames by the Wi2Vi provide auxiliary information to the conventional surveillance system in critical circumstances. Our implementation of the Wi2Vi system confirms the feasibility of constructing a system capable of deriving the correlations between measurements in different frequency spectrums.

    • We have done the same and published back in early 2020. THis paper does reference our work as [11]. Blog post with our human detection video here (eerie !): https://futurebnd.com/human-detection-classification-and-vis... and the paper here: https://arxiv.org/pdf/2001.05842.pdf
