Estimating Surface Normals from Spherical Stokes Reflectance Fields
نویسندگان
چکیده
In this paper we introduce a novel technique for estimating surface normals from the four Stokes polarization parameters of specularly reflected light under a single spherical incident lighting condition that is either unpolarized or circularly polarized. We illustrate the practicality of our technique by estimating surface normals under uncontrolled outdoor illumination from just four observations from a fixed viewpoint.

A neural network approach to photometric stereo inversion of real-world reflectance maps for extracting 3-D shapes of objects
Presents a neural network approach to the problem of photometric stereo inversion of the reflectance maps of real-world objects for the purpose of estimating the 3-D attitudes of the surface patches of objects. As in the photometric stereo approach, here also the observation that there is a one-to-one mapping between the n-tuples of the photometric stereo image intensities and the orientations ...
متن کاملFace Shape and Reflectance Acquisition using a Multispectral Light Stage
In this thesis, we discuss the design and calibration (geometric and radiometric) of a novel shape and reflectance acquisition device called the “Multispectral Light Stage”. This device can capture highly detailed facial geometry (down to the level of skin pores detail) and Multispectral reflectance map which can be used to estimate biophysical skin parameters such as the distribution of pigmen...
متن کاملReshading Light Fields
A category of methods usually called Image Based rendering has appeared recently to produce realistic images of objects. Instead of creating models from geometric primitives which are then rendered according to the point of view and the illumination given, the light reflected/emitted from objects is captured from enough different points of view to be able to reconstruct the light received from ...
متن کاملSurface shape and reflectance analysis using polarisation
When unpolarised light is reflected from a smooth dielectric surface, it becomes partially polarised. This is due to the orientation of dipoles induced in the reflecting medium and applies to both specular and diffuse reflection. This thesis aims to exploit the polarising properties of surface reflection for computer vision applications. Most importantly, the thesis proposes novel shape and ref...
متن کاملSimultaneous Estimation of Spectral Reflectance and Normal from a Small Number of Images
Spectral reflectance is inherent characteristics of an object surface and therefore useful not only for computer vision tasks such as material classification but also compute graphics applications such as relighting. In this study, by integrating multispectral imaging and photometric stereo, we propose a method for simultaneously estimating the spectral reflectance and normal per pixel from a s...
