21Oren–Nayar reflectance model — The Oren Nayar reflectance model, developed by Michael Oren and Shree K. Nayar, is a reflectance model for diffuse reflection from rough surfaces. It has been shown to accurately predict the appearance of a wide range of natural surfaces, such as …
22Oren–Nayar Reflectance Model — The Oren Nayar model, developed by Michael Oren and Shree K. Nayar, is a reflectance model for diffuse reflection from rough surfaces. It has been shown to accurately predict the appearance of a wide range of natural surfaces, such as concrete,… …
23Bidirectional reflectance distribution function — The bidirectional reflectance distribution function (BRDF; {f r(omega i , omega o) }) is a 4 dimensional function that defines how light is reflected at an opaque surface. The function takes an incoming light direction, omega i , and outgoing… …
24Lambertian reflectance — If a surface exhibits Lambertian reflectance, light falling on it is scattered such that the apparent brightness of the surface to an observer is the same regardless of the observer s angle of view. More technically, the surface luminance is… …
25Empirical reflectance retrieval — is a technique in satellite imaging for determining the reflectance of unknown targets by comparison with those areas whose reflectance is independently known. The concept of Empirical Reflectance Retrieval was developed to address the difficulty …
26Martian surface — The study of surface characteristics (or surface properties and processes[1]) is a broad category of Mars science that examines the nature of the materials making up the Martian surface. The study evolved from telescopic and remote sensing… …
27Attenuated total reflectance — (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation.cite web | year=2005 | title=FT IR Spectroscopy Attenuated Total… …
28Directional-hemispherical reflectance — is the reflectance of a surface under direct illumination (with no diffuse component). Directional hemispherical reflectance is the integral of the BRDF over all viewing directions. It is sometimes called black sky albedo . See also: Bi… …
29Bi-hemispherical reflectance — is the reflectance of a surface under diffuse illumination (with no direct component). Bi hemispherical reflectance is the integral of the BRDF over all viewing and illumination directions of a hemisphere. It is sometimes called white sky albedo …
30Light Reflectance Value — Light Reflectance Value, or LRV, is a measurement commonly used in interior decorating and design, which expresses the percentage of light that is reflected from a surface.LRV is frequently included on the backs of paint chips or samples and is… …
