Deep shape from polarization

Y Ba, A Gilbert, F Wang, J Yang, R Chen… - Computer Vision–ECCV …, 2020 - Springer
This paper makes a first attempt to bring the Shape from Polarization (SfP) problem to the
realm of deep learning. The previous state-of-the-art methods for SfP have been purely …

Polarimetric multi-view stereo

Z Cui, J Gu, B Shi, P Tan… - Proceedings of the IEEE …, 2017 - openaccess.thecvf.com
Multi-view stereo relies on feature correspondences for 3D reconstruction, and thus is
fundamentally flawed in dealing with featureless scenes. In this paper, we propose …

Recovery of surface orientation from diffuse polarization

GA Atkinson, ER Hancock - IEEE transactions on image …, 2006 - ieeexplore.ieee.org
When unpolarized light is reflected from a smooth dielectric surface, it becomes partially
polarized. This is due to the orientation of dipoles induced in the reflecting medium and …

Event-based shape from polarization

M Muglikar, L Bauersfeld, DP Moeys… - Proceedings of the …, 2023 - openaccess.thecvf.com
State-of-the-art solutions for Shape-from-Polarization (SfP) suffer from a speed-resolution
tradeoff: they either sacrifice the number of polarization angles measured or necessitate …

Depth from a polarisation+ RGB stereo pair

D Zhu, WAP Smith - … of the IEEE/CVF conference on …, 2019 - openaccess.thecvf.com
In this paper, we propose a hybrid depth imaging system in which a polarisation camera is
augmented by a second image from a standard digital camera. For this modest increase in …

Linear depth estimation from an uncalibrated, monocular polarisation image

WAP Smith, R Ramamoorthi, S Tozza - … 11-14, 2016, Proceedings, Part VIII …, 2016 - Springer
We present a method for estimating surface height directly from a single polarisation image
simply by solving a large, sparse system of linear equations. To do so, we show how to …

Height-from-polarisation with unknown lighting or albedo

WAP Smith, R Ramamoorthi… - IEEE transactions on …, 2018 - ieeexplore.ieee.org
We present a method for estimating surface height directly from a single polarisation image
simply by solving a large, sparse system of linear equations. To do so, we show how to …

Multi-view azimuth stereo via tangent space consistency

X Cao, H Santo, F Okura… - Proceedings of the IEEE …, 2023 - openaccess.thecvf.com
We present a method for 3D reconstruction only using calibrated multi-view surface azimuth
maps. Our method, multi-view azimuth stereo, is effective for textureless or specular …

Surface normal estimation of black specular objects from multiview polarization images

D Miyazaki, T Shigetomi, M Baba… - Optical …, 2017 - spiedigitallibrary.org
Polarization is a phenomenon that cannot be observed by the human eye, but it provides
rich information regarding scenes. The proposed method estimates the surface normal of …

Shape estimation using polarization and shading from two views

GA Atkinson, ER Hancock - IEEE transactions on pattern …, 2007 - ieeexplore.ieee.org
This paper presents a novel method for 3D surface reconstruction that uses polarization and
shading information from two views. The method relies on the polarization data acquired …
