  • Bidirectional 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… …   Wikipedia

  • Lambertian 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… …   Wikipedia

  • Empirical 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 …   Wikipedia
