TRACE: 5D Temporal Regression of Avatars with Dynamic Cameras in 3D Environments

Figure 1. 5D temporal reconstruction of multiple 3D people in global coordinates with a dynamic camera. We introduce TRACE, a monocular one-stage method with a holistic 5D representation that enables the network to explicitly reason about human motion across time. Unlike previous methods [45,46] (b) that regress all 3D people from each frame in camera coordinates, TRACE (c) tracks the subjects (a) presented in the first frame through time and recovers their global trajectories in global coordinates in one shot.
