Scientists from Carnegie Mellon University have developed a cheap way to sense humans through walls by using two Wi-Fi routers to image ... is projected to a 2D image for mapping a computer ...

All they needed was a pair of entry-level routers ... the image you see above -- for that, researchers had to turn to an AI model called DensePose that estimates body position from 2D photos.

The research team has several general Wi-Fi transmitters such as those installed in the TP-Link Wi-Fi router Archer A7 AC1750 ... estimate human posture from 2D images and map textures to the ...
