Two-frequency phase-shifting phase unwrap** and Gray-coded-based phase unwrap**
are two typical temporal phase unwrap** methods to recover discontinuous or spatially …

This paper reviews the state-of-the-art methodologies for develo** computer-aided design
(CAD) model based systems for assembly simulation, planning and training. Methods for …

Time-of-flight (TOF) cameras provide a depth value at each pixel, from which the 3D
structure of the scene can be estimated. This new type of active sensor makes it possible to …

There is an increasing need for passive 3D scanning in many applications that have
stringent energy constraints. In this paper, we present an approach for single frame, single …

Depth measurement and three-dimensional (3D) imaging under complex reflection and
transmission conditions are challenging and even impossible for traditional structured light …

The aim of this study is to gain basic information about matte coating thickness in the area of
3D optical digitization. Thickness measurement was performed for two matting materials; …

We consider the problem of deliberately manipulating the direct and indirect light flowing
through a time-varying, fully-general scene in order to simplify its visual analysis. Our …

Translucent materials are ubiquitous, and simulating their appearance requires accurate
physical parameters. However, physically-accurate parameters for scattering materials are …

This paper presents a novel structured light approach for the 3D reconstruction of specular
surface. The binary shifting strip is adopted as structured light pattern instead of …

We consider the problem of shape recovery for real world scenes, where a variety of global
illumination (inter-reflections, subsurface scattering, etc.) and illumination defocus effects are …
