If I understand the captions correctly, the wireframe images overlaid on RGB images are from the algorithm run on the RGB images, not the wifi data, so having them match up is not surprising.
The standalone wireframe images sometimes manage to get the number of people and their approximate positions correct, but everything else about them seems (IMO) believable but not necessarily accurate, like most AI output.
This doesn't surprise me, because the input data is very coarse. Look at their graphs. There's just not enough raw data there to accurately reconstruct much other than position in the room.
I'm sure it's possible to do more accurate recording and reconstruction, I just don't think this demonstrates it.
