Reflectance and illumination
WebThe approach is inspired by the fact that reflectance and illumination are highly correlated to satisfy the well-known Retinex decomposition principle. With this in mind, we establish a Reflectance-and-Illumination Collaborative (RIC) block to depict the compact physical relationship between reflectance and illumination. WebInferring object reflectance and scene illumination from an image would help us decode this information: reflectance can reveal important properties about the materials composing …

WebThe final product is a nearly illumination independent measure of the water’s reflectance, known as remote sensing reflectance. In oceanography, satellites are used to calculate the same product (remote sensing reflectance) from space. The reflectance is directly related to the amount and type of suspended particles in the water. Web1. jún 2016 · Another type of traditional methods is Retinex-based method (Land, 1977), which is based on the assumption that the image can be decomposed into reflection and illumination, e.g., single-scale...

With this in mind, we establish … WebSpectral reflectance is the ratio of reflected energy to incident radiation (ɸ r /ɸ) as a function of the wavelength. The spectral reflectance characteristics of most targets depend upon the illuminating region of the EM spectrum. The MSS, TM, LISS are some of the sensors to sense the radiances at distinct spectral bandwidths.
