a 3D visual-semantic map of the indoor environment. b Snapshots of 4D imaging results for different laboratory scenes involving two freely acting human subjects. The corresponding optical images are shown in the first row and the reconstructions based on the semantic embedding proposed by the encoder network are shown in the second row. The text in parentheses describes the body language meaning of the action. The third row shows snapshots of semantically altered reconstructions, and the corresponding modified semantic controls are indicated. c Histogram of the RMSE distribution comparing the reconstructed 4D skeletons to the corresponding ground truths, based on 10,000 samples for testing.
