In this paper, we present a technique for estimating the geometry and reflectance of objects
using only a camera, flashlight, and optionally a tripod. We propose a simple data capture …

We conduct a thorough study of photometric stereo under nearby point light source
illumination, from modeling to numerical solution, through calibration. In the classical …

We introduce coded two-bucket (C2B) imaging, a new operating principle for computational
sensors with applications in active 3D shape estimation and coded-exposure imaging. A …

Estimating 3D surface normals through photometric stereo has been of great interest in
computer vision research. Despite the success of existing traditional and deep learning …

In this paper we present a differential approach to photo-polarimetric shape estimation. We
propose several alternative differential constraints based on polarisation and photometric …

Shape from shading with multiple light sources is an active research area, and a diverse
range of approaches have been proposed in recent decades. However, devising a robust …

Photometric 3D-reconstruction techniques aim at inferring the geometry of a scene from one
or several images, by inverting a physical model describing the image formation. This …

In this paper we present methods for estimating shape from polarisation and shading
information, ie photo-polarimetric shape estimation, under varying, but unknown …

An optimal, in the least squares sense, method is proposed to estimate surface normals in
both stereo and multi-view cases. The proposed algorithm exploits exclusively photometric …

There is provided a method and system for pixel-wise imaging of a scene. The method
including: receiving a pixel-wise pattern, the pixel-wise pattern including a mask ing value …
