ŠT—v/Abstract

We propose an advanced visual hull technique to compensate for outliers using the reliabilities of the silhouettes. The proposed method consists of a background subtraction technique using multiple thresholds and a reliability-based shape-from-silhouette algorithm. They are connected by the intra-/inter-silhouette reliabilities to compensate for carving errors from defective segmentation or partial occlusion which may occur in real environments. In final view rendering, we use a cinematographic camera control system and an ARToolkit to control virtual cameras.
