Accurate 3D Footwear Impression Recovery From Photographs
The recovery of footwear impression in crime scenes plays an important role in investigations to corroborate or refute information, or to narrow down the number of suspects. Casting 3D footwear impressions is a long-standing standard to obtain the 3D models of the prints, slowly being replaced by a less invasive method, 3D scanning. In this paper, we present an alternative method based on multi...
متن کاملSilhouette-Based 3D Face Shape Recovery
The creation of realistic 3D face models is still a fundamental problem in computer graphics. In this paper we present a novel method to obtain the 3D shape of an arbitrary human face using a sequence of silhouette images as input. Our face model is a linear combination of eigenheads, which are obtained by a Principal Component Analysis (PCA) of laser-scanned 3D human faces. The coefficients of...
متن کاملShading Based 3D Shape Recovery in the Presence of Shadows
Shadows usually cause various problems in three-dimensional shape recovery and measurement methods. In particular shading based approaches such as shape-from-shading or the photometric stereo method produce no or wrong results if the shadows are not treated appropriately. We show how information extracted from shadows can be employed to reduce the problems caused by them. This is done for multi...
متن کاملWhat Do Photographs Tell Us About 3D Shape?
In this paper we consider the problem of computing the 3D shape of an unknown, arbitrarily-shaped scene from multiple color photographs taken at known but arbitrarilydistributed viewpoints. By studying the equivalence class of all 3D shapes that reproduce the input photographs, we prove the existence of a special member of this class, the maximal photo-consistent shape, that (1) can be computed...
