Also, they were able to use Wi-Fi to sense humans and their pose, rather than just being able to only accurately locate an object in a room. &nbsp; &nbsp;<\/p>\n<p>&#8220;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 Wi-Fi signals as the only input. This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing,&#8221; researchers Jiaqi Geng, Dong Huang, and Fernando De la Torre explain in their paper,&nbsp;<a href=\"https:\/\/arxiv.org\/abs\/2301.00250\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">DensePose From WiFi<\/a>.&nbsp;<\/p>\n<p>The researchers ague that their Wi-Fi approach to imaging humans in households could be applied to home healthcare, where patients may not want to be monitored with a camera in places like the bathroom or with other sensors and tracking devices.&nbsp;<\/p>\n<p>Importantly, the Wi-Fi-monitoring system is not impacted by poor light or obstructions, such as walls. Also, it requires a very cheap setup, using equipment most people have at home already. The two TP Link Wi-Fi routers used in the study cost about $30 each, versus around $700 for the most common LiDAR.<\/p>\n<p>&#8220;We believe that Wi-Fi signals can serve as a ubiquitous substitute for RGB images for human sensing in certain instances. Illumination and occlusion have little effect on Wi-Fi-based solutions used for interior monitoring. In addition, they protect individuals&#8217; privacy and the required equipment can be bought at a reasonable price,&#8221; the researchers write.&nbsp;<\/p>\n<p><strong>Also:&nbsp;<\/strong><a

identify suspicious behaviors at home.&#8221;<\/p>\n<p>As the researchers note, there is a lot of literature on detection, tracking, and dense pose estimation from images and video, but very little on the subject of human pose estimation from Wi-Fi or radar.&nbsp;<\/p>\n<p>READ MORE <a
