Preserved Fulltext
We present a novel method for accurate marker-less capture of articulated skeleton motion of several subjects in general scenes, indoors and outdoors, even from input filmed with as few as two cameras. ...
In combination, this enables to track full articulated joint angles at state-of-the-art accuracy and temporal stability with a very low number of cameras. ...
This paper describes a new method to fuse marker-less skeletal motion tracking with body part detections from a convolutional network (ConvNet) for efficient and accurate marker-less motion capture with ...
