| abstract | = | "We present a system for rendering novel viewpoints from a set of calibrated and silhouette-segmented images
using the visual hull together with multi-view stereo. The visual hull predicted from the object silhouettes is
used to restrict the search range of the multi-view stereo. This reduces redundant computation and the
possibility of incorrect matches. Unlike previous visual hull approaches, we do not need to recover a polyhedral
model. Instead, the visual hull is implicitly described by the silhouette images and synthesized using their
projections onto a set of planes. This representation allows an efficient implementation on current pixel-shader
graphics cards, yielding frames at interactive rates. We also introduce a library of image filters to improve
rendering results along edges and silhouette profiles.", |
