DETECTION-GUIDED TRACKING OF HUMAN DYNAMICS

Abstract:

A system and method for detection-guided tracking of human-dynamics is provided. The system receives an input human-dynamics sequence including geometry information and an RGB video of a human object. The system inputs the RGB video to the neural network and estimates a pose of the human object in each frame of the RGB video based on output of the neural network for the input. The system selects, from the input human-dynamics sequence, a key-frame for which the estimated pose is closest to a reference human pose. From the selected key-frame and up to a number of frames of the input human-dynamics sequence, the system generates a tracking sequence for a 3D human mesh of the human object. The generated tracking sequence includes final values of parameters of articulate motion and non-rigid motion of the 3D human mesh. Based on the generated tracking sequence, the system generates a free-viewpoint video.
