Normalized radiance
Radiant intensity, denoted Ie,Ω ("e" for "energetic", to avoid confusion with photometric quantities, and "Ω" to indicate this is a directional quantity), is defined as where • ∂ is the partial derivative symbol; • Φe is the radiant flux emitted, reflected, transmitted or received; Web/** Evaluates the radiance outgoing at a surface in the world. We assume a perfect Lambertian diffuse lobe, as that is the only case that can be correctly factored out and multiplied by preintegrated irradiance. Note that this is an approximation to actual directional diffuse BSDF lobe used elsewhere. \param[in] posW World-space position.

Data Acquisition Methods Web13 de jan. de 2024 · The deep learning based HDR generation method is adopted to map a single low dynamic range (LDR) image into a radiance map which is normalized to exclude the influence of exposure time. We retrained the ORB descriptor patch to fit the normalized radiance maps in the feature matching step.
