Spectral analysis of natural scenes can provide much more detailed information about the
scene than an ordinary RGB camera. The richer information provided by hyperspectral …

This paper theorizes the connection between polarization and three-view geometry. It presents
a ubiquitous polarization-induced constraint that regulates the relative pose of a system …

Spectral photoacoustic imaging (PAI) is a new technology that is able to provide 3D geometric
structure associated with 1D wavelength-dependent absorption information of the interior …

This paper presents a precise, stable, and invertible reflectance model for photometric
stereo. This microfacet-based model is applicable to all types of isotropic surface reflectance, …

A precise, stable and invertible model for surface reflectance is the key to the success of
photometric stereo with real world materials. Recent developments in the field have enabled …

Previous research showed that the separation of direct and global components could be done
with a single image by assuming neighboring scene points have similar direct and global …

Direct and global component separation is an approach to study the light transport that
provides a basic understanding of the property of a scene. The conventional technique for …

Object placement relation (OPR) is the information set representing relationship between
set of image components. It can be applied for constructing various types of image scenes …

Object Placement Relation (OPR) is the set of properties with classified relations between two
connected objects. OPR has been used to predict depth level and locate position of object …

The spectral reflectance (SR) of objects provides innate information about material properties
that have proven useful in applications such as classification, synthetic relighting, and …
