Brownian motion — This article is about the physical phenomenon; for the stochastic process, see Wiener process. For the sports team, see Brownian Motion (Ultimate). For the mobility model, see Random walk. Brownian motion (named after the botanist Robert Brown)… … Wikipedia
Brownian motion — Any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for Robert Brown, who was investigating the fertilization process of flowers in 1827 when he noticed a rapid oscillatory… … Universalium
Fractional Brownian motion — A normalized fractional Brownian motion (denoted fBm) B^H(t) on [0,T] , Tin mathbb{R} is a continuous time Gaussian process starting at zero, with mean zero, and having the following correlation function::E [B^H(t) B^H(s)] =frac{1}{2}… … Wikipedia
Geometric Brownian motion — A geometric Brownian motion (GBM) (occasionally, exponential Brownian motion) is a continuous time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion, or a Wiener process. It is applicable to… … Wikipedia
Motion analysis — is a topic in computer vision, image processing, and machine vision that studies methods and applications in which two or more consecutive images from an image sequences, e.g., produced by a video camera, are processed to produce information… … Wikipedia
Brownian bridge — A Brownian bridge is a continuous time stochastic process whose probability distribution is the conditional probability distribution of a Wiener process B ( t ) (a mathematical model of Brownian motion) given the condition that B (0) = B (1) = 0 … Wikipedia
Brownian tree — A Brownian tree, whose name is derived from Robert Brown via Brownian motion, is a form of computer art that was briefly popular in the 1990s, when home computers started to have sufficient power to simulate Brownian motion. Brownian trees are… … Wikipedia
motion — motional, adj. motioner, n. /moh sheuhn/, n. 1. the action or process of moving or of changing place or position; movement. 2. power of movement, as of a living body. 3. the manner of moving the body in walking; gait. 4. a bodily movement or… … Universalium

Wiener process — In mathematics, the Wiener process is a continuous time stochastic process named in honor of Norbert Wiener. It is often called Brownian motion, after Robert Brown. It is one of the best known Lévy processes (càdlàg stochastic processes with… … Wikipedia
