Global illumination — is a general name for a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes. Such algorithms take into account not only the light which comes directly from a light source ( direct… … Wikipedia
Constellation model — The constellation model is a probabilistic, generative model for category level object recognition in computer vision. Like other part based models, the constellation model attempts to represent an object class by a set of N parts under mutual… … Wikipedia
Oren–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 … Wikipedia
Color model — A color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. When this model is associated with a precise description of how the… … Wikipedia
Counter-illumination — Counterillumination is a method of camouflage in which bioluminescent light from within an organism is matched to the light radiating from an environmental source in order to obscure the organism s silhouette produced by the environmental… … Wikipedia
Single Vegetative Obstruction Model — The ITU Single Vegetative Obstruction Model is a Radio propagation model that quantitatively approximates the attenuation due to the vegetation in the middle of a telecommunication link. Applicable to/under conditionsThe model is applicable to… … Wikipedia
dual-input model of hallucinations — A term used to denote a hypothetical model for the mediation of hallucinations that was formulated during the 1960s by the American psychiatrist Louis Jolyon West (1924 1999). Basically, the dual input model would seem to constitute a variant… … Dictionary of Hallucinations
Dichromatic reflectance model — In Shafer’s dichromatic reflection model, scene radiance has two components: cb is the body reflected component cs is the surface reflected component mb and ms are scale factors depending on illumination, view directions and surface orientation.… … Wikipedia
