This paper presents a fully automated system for realtime 3D human visual hull reconstruction and skeleton voxels extraction. The main contributions include: (1) A novel network based system is presented, which uses AXIS network cameras as video capture device, and performs a parallel processing among data capture, 3D voxel reconstruction and display. (2) A new human visual hull reconstruction algorithm is given. This approach firstly segments the foreground accurately by an efficient Gaussian

Experiments with real video sequences show that the system can process eleven 640x480 video sequences at a frame rate of 15fps, and construct human body voxels reliably in complex scenarios with cast shadows, various body configurations and multiple persons.
