An Active Multi-camera Motion Capture for Face, Fingers and Whole Body
説明
This paper explores a novel endeavor of deploying only four active-tracking cameras and fundamental vision-based technologies for 3D motion capture of a full human body figure, which includes facial expression, motion of fingers of both hands and a whole body. The proposed methods suggest alternatives to extract motion parameters of the mentioned body parts from four single-view image sequences. The proposed ellipsoidal model- and flow-based facial expression motion capture solution tackles both 3D head pose and non-rigid facial motion effectively and we observe that a set of 22 self-defined feature points suffice the expression representation. The body figure and fingers motion capture is solved with a combination of articulated model and flow-based methods.
