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

, 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

DirectX 11 -grafiikkamoottori ja BRDF-mallit [PDF]

, 2017
Opinnäytetyön tavoitteena oli luoda grafiikkamoottori, jolla voidaan esitellä yleisempiä tietokonegrafiikassa käytettyjä BRDF-malleja. Työssä luotu grafiikkamoottori suunniteltiin niin, että sillä on helppo valita eri BRDF-malleja tarkastelua varten ...

BRDF rendering by interpolation of optimised model parameters

, 2020
In this paper, we discuss an interpolation method which can be used to create a look up table to map tristimulus values to BRDF parameters. For a given tristimulus value, we interpolate the XYZ lattice formed by eight primaries and secondaries that were ...

Hypernetworks for Generalizable BRDF Representation

In this paper, we introduce a technique to estimate measured BRDFs from a sparse set of samples. Our approach offers accurate BRDF reconstructions that are generalizable to new materials. This opens the door to BDRF reconstructions from a variety of data sources.

Synergizing BRDF correction and deep learning for enhanced crop classification in GF-1 WFV imagery

Frontiers in Remote Sensing
Accurate crop classification is essential for agricultural management, resource allocation, and food security monitoring. GF-1 Wide Field View (WFV) imagery suffers from Bidirectional Reflectance Distribution Function (BRDF) effects due to large viewing ...

Multi-Level Spectral Attention Network for Hyperspectral BRDF Reconstruction from Multi-Angle Multi-Spectral Images

Remote Sensing
With the rapid development of hyperspectral applications using unmanned aerial vehicles (UAVs), the traditional assumption that ground objects exhibit Lambertian reflectance is no longer sufficient to meet the high-precision requirements for quantitative
