Markerless Motion Capture in the Crowd
This work uses crowdsourcing to obtain motion capture data from video
recordings. The data is obtained by information workers who click repeatedly to
indicate body configurations in the frames of a video, resulting in a model of
2D structure over time. We discuss techniques to optimize the tracking task and
strategies for maximizing accuracy and efficiency. We show visualizations of a
variety of motions captured with our pipeline then apply reconstruction
techniques to derive 3D structure.Comment: Presented at Collective Intelligence conference, 2012
