Facial appearance capture is now firmly established within academic research and used
extensively across various application domains, perhaps most prominently in the …

Understanding as well as realistic reproduction of the appearance of materials play an
important role in computer graphics, computer vision and industry. They enable applications …

We propose a non-permanent add-on that enables plenoptic imaging with standard
cameras. Our design is based on a physical copying mechanism that multiplies a sensor …

Strong ambient illumination severely degrades the performance of structured light based
techniques. This is especially true in outdoor scenarios, where the structured light sources …

Bidirectional Texture Functions (BTFs) are able to represent complex materials with greater
generality than traditional analytical models. This holds true for both measured real …

The demands for digital 3D content for numerous applications such as video games, movies,
virtual prototyping, advertisement, virtual reality, augmented reality or even digital …

Abstract Bidirectional Texture Functions (BTFs) provide a realistic depiction of the
appearance of many real-world materials as they contain the spatially varying light …

In standard photography, vignetting is considered mainly as a radiometric effect because it
results in a darkening of the edges of the captured image. In this paper, we demonstrate that …

Full surround 3D imaging for shape acquisition is essential for generating digital replicas of
real-world objects. Surrounding an object we seek to scan with a kaleidoscope, that is, a …

Mirroring is one of the fundamental light/surface interactions occurring in the real world.
Surfaces often cause specular reflection, making it necessary to design robust geometry …
