Motion capture systems do not have enough degrees of freedom
to capture moving cloth. Our system recovers the geometry and
parameterisation of a sheet of moving cloth by using stereo correspondence
and an extension of the scale-invariant feature transform
(SIFT) introduced by Lowe [1999]. Previous work on cloth capture
[Guskov 2002] required a checkerboard pattern to be printed on the
cloth, and recovered much fewer features.
