Characterization of Scale Effects and Determination of Optimal Observation Scales for Bidirectional Reflectance in High-Resolution Remote Sensing of Land Surfaces

Remote Sensing
Land surface bidirectional reflectance distribution functions (BRDF) are critical for quantitative remote sensing but are significantly constrained by scale effects, limiting the interoperability of multi-resolution data and the accuracy of quantitative ...

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

Real-Time Linear BRDF MIP-Mapping

, 2017
We present a new technique to jointly MIP-map BRDF and normal maps. Starting with generating an instant BRDF map, our technique builds its MIP-mapped versions based on a highly efficient algorithm that interpolates von Mises-Fisher (vMF) distributions ...

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 ...
