In the human system distorted cylinders are common, and geometry can be reconstructed from local measures of curvature. An algorithm is presented to reconstruct the shape of a surface from a series of curvature measurements. The Abrams Gentile Entertainment patented bend sensor was evaluated as a curvature transducer. The sensor was tested at the extremes of the likely measurement range, from curvatures below 0.01 mm−1 up to a curvature of 0.1 mm−1. The upper curvature limit proved beyond the design specification of the sensor. The technique was applied at the lower curvature range to reconstruct one quadrant of the chest of a volunteer and record breathing movement. The bend sensor is inexpensive and can be applied to obtain an approximate reconstruction of surface geometry in the human system.

Multiple wide baseline views are integrated into a view-dependent representation based on pair wise refinement of the visual-hull. An exact view- dependent visual-hull (VDVH) algorithm is presented to compute an initial approximation of the scene geometry. Refinement of the VDVH surface is

Ultimately the 3D Virtual Studio should enable video-realistic recon- struction of a moving person from any viewpoint. A mesh-based stereo technique is presented to reconstruct a moving person from multiple camera views. This technique optimises a

Human shape reconstruction is considered where extended regions of uniform ap- pearance, complex self-occlusions and sparse feature cues represent a chal- lenging problem for conventional reconstruction techniques. A unified ap- proach is introduced
