Recent progress on photometric stereo extends the technique to deal with general materials
and unknown illumination conditions. However, due to the lack of suitable benchmark data …

Coarse depth maps can be enhanced by using the shape information from polarization
cues. We propose a framework to combine surface normals from polarization (hereafter …

The popularity of low-cost RGB-D scanners is increasing on a daily basis. Nevertheless,
existing scanners often cannot capture subtle details in the environment. We present a novel …

Geometric surface information such as depth maps and surface normals can be acquired by
various methods such as stereo light fields, shape from shading and photometric stereo …

Analyzing the polarimetric properties of reflected light is a potential source of shape
information. However, it is well-known that polarimetric information contains fundamental …

We present a novel framework to estimate detailed shape of diffuse objects with uniform
albedo from a single RGB-D image. To estimate accurate lighting in natural illumination …

We propose a robust uncalibrated multiview photometric stereo method for high quality 3D
shape reconstruction. In our method, a coarse initial 3D mesh obtained using a multiview …

We investigate the problem of reconstructing normals, albedo and lights of Lambertian
surfaces in uncalibrated photometric stereo under the perspective projection model. Our …

We present a calibration method of a time-of-flight (ToF) sensor and a color camera pair to
align the 3D measurements with the color image correctly. We have designed a 2.5 D …

In this work we solve the uncalibrated photometric stereo problem with lights placed near the
scene. We investigate different image formation models and find the one that best fits our …
