BRDF and gloss measurements [PDF]

open access: yes, 2007
Gloss is an important aspect of our visual perception of objects. Many developments of gloss measurement have been carried out as part of the technical work of the ASTM, resulting in the ASTM method D523.

In Praise of an Alternative BRDF Parametrization.

open access: yes, 2015
In this paper, we extend the work of Neumann et al. [NNSK99] and Stark et al. [SAS05] to a pair of 4D BRDFparameterizations with explicit changes of variables. We detail their mathematical properties and relationships tothe commonly-used halfway/difference parametrization, and discuss their benefits and drawbacks using a few an-alytical test functions ...

Evaluation of MODIS and VIIRS BRDF Parameter Differences and Their Impacts on the Derived Indices

open access: yesRemote Sensing
Multi-angle remote sensing observations play an important role in the remote sensing of solar radiation absorbed by land surfaces. Currently, the Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS ...

The development of a temporal-BRDF model-based approach to change detection, an application to the identification and delineation of fire affected areas. [PDF]

open access: yes, 2006
Although large quantities of southern Africa burn every year, minimal information is available relating to the fire regimes of this area. This study develops a new, generic approach to change detection, applicable to the identification of land cover ...

A BRDF-BPDF database for the analysis of Earth targets reflectances

open access: yes, 2016
A database of representative BRDF and BPDF derived from the POLDER measurements. From the huge amount of data acquired by the spaceborne instrument over a period of 7 years, we selected a set of targets with high quality observations. The selection aimed

Deep Image-Based Adaptive BRDF Measure

open access: yes
Efficient and accurate measurement of the bi-directional reflectance distribution function (BRDF) plays a key role in realistic image rendering. However, obtaining the reflectance properties of a material is both time-consuming and challenging.
