WebThe standard deviations of the Gaussian filter are given for each axis as a sequence, or as a single number, in which case it is equal for all axes. The order of the filter along each axis is given as a sequence of integers, or as a single number. An order of 0 corresponds to convolution with a Gaussian kernel. In mathematics, a Gaussian function, often simply referred to as a Gaussian, is a function of the base form Gaussian functions are often used to represent the probability density function of a normally distributed random variable with expected value μ = b and variance σ = c . In this case, the … See more Gaussian functions arise by composing the exponential function with a concave quadratic function: • $${\displaystyle \alpha =-1/2c^{2},}$$ • $${\displaystyle \beta =b/c^{2},}$$ See more A number of fields such as stellar photometry, Gaussian beam characterization, and emission/absorption line spectroscopy work with sampled Gaussian functions … See more Gaussian functions appear in many contexts in the natural sciences, the social sciences, mathematics, and engineering. Some examples include: • In statistics and probability theory, Gaussian functions appear as the density function of the See more • Mathworld, includes a proof for the relations between c and FWHM • "Integrating The Bell Curve". MathPages.com. • Haskell, Erlang and Perl implementation of Gaussian distribution See more Base form: In two dimensions, the power to which e is raised in the Gaussian function is any negative-definite quadratic form. Consequently, the level sets of the Gaussian will always be ellipses. A particular … See more One may ask for a discrete analog to the Gaussian; this is necessary in discrete applications, particularly digital signal processing. A simple answer is to sample the continuous Gaussian, yielding the sampled Gaussian kernel. However, this discrete function … See more • Normal distribution • Lorentzian function • Radial basis function kernel See more
