Capturing and Animating Occluded Cloth
To appear in SIGGRAPH 2007
Abstract:We capture the shape of moving cloth using a custom set of color
markers printed on the surface of the cloth. The output is a sequence
of triangle meshes with static connectivity and with detail at the
scale of individual markers in both smooth and folded regions. We
compute markers' coordinates in space using marker correspondence
across multiple synchronized video cameras. Correspondence is
determined from color information in small neighborhoods and refined
using a novel strain pruning process. Final correspondence
does not require neighborhood information. We use a novel data
driven hole-filling technique to fill occluded regions. Our results
include several challenging examples: a wrinkled shirt sleeve, a
dancing pair of pants, and a rag tossed onto a cup. Finally, we demonstrate that
cloth capture is reusable by animating a pair of pants using human
motion capture data.
