For this, the DensePose system was used, which captures people according to image markers.

Researchers from Carnegie Mellon University have created a method that can be used to see the three-dimensional human figure and the movement of people behind the walls of the area. This happens with the help of Wi-Fi routers, according to Vice.

In their work, the scientists used the DensePose system. He draws people according to the markers from the picture.

Now, experts have implemented a neural network in their method that compares data from Wi-Fi signals sent and received by routers with a person’s coordinates.

“Wi-Fi signals are great as a replacement for standard RGB cameras if you need to draw or see people behind obstacles. In addition to obstacles, their method also helps with weak illumination. It seems that such a discovery puts people’s privacy at risk again. But the development should help implement surveillance systems to monitor the well-being of elderly people or simply to detect suspicious activity. behavior in a protected area,” the study authors said.
