Through-Wall Human Pose Estimation Using Radio Signals

With the new computer vision algorithm based on the fact that a wireless signal can pass through walls but is reflected off humans, it is thus possible to spy on people behind a wall. This article demonstrates that tracking the human motions by a radio-based system can be almost as accurate as the vision-based one used to train it. The major limitation for this technology is that the wireless signal data has a way lower spatial resolution compared to the vision one. But even regardless of this fact, we can not underestimate its multifaceted applicability!
