flat function
1Flat-field correction — is a technique used to improve quality in digital imaging. The goal is to remove artifacts from 2 D images that are caused by variations in the pixel to pixel sensitivity of the detector and/or by distortions in the optical path. It is a standard …
2flat — adj, flat·ter; flat·test 1) being or characterized by a horizontal line or tracing without peaks or depressions <the EEG is ominously flat indicating that her brain function is gone (Don Gold)> 2) characterized by general impoverishment in… …
3Flat tax — A flat tax (short for flat rate tax) is a tax system with a constant tax rate. [James, Simon (1998) A Dictionary of Taxation , Edgar Elgar Publishing Limited: Northampton, MA] Usually the term flat tax would refer to household income (and… …
4Flat spline — A spline consists of a long strip fixed in position at a number of points that relaxes to form a smooth curve passing through those points.Before computers were used for creating engineering designs, drafting tools were employed by designers… …
5Window function — For the term used in SQL statements, see Window function (SQL) In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero valued outside of some chosen interval …
6Optical transfer function — The optical transfer function (OTF) of an imaging system (camera, video system, microscope etc) is the true measure of resolution (image sharpness) that the system is capable of. The common practice of defining resolution in terms of pixel count… …
7Transfer function — A transfer function (also known as the system function[1] or network function) is a mathematical representation, in terms of spatial or temporal frequency, of the relation between the input and output of a linear time invariant system. With… …
8Conformally flat manifold — A (pseudo )Riemannian manifold is conformally flat if each point has a neighborhood that can be mapped to flat space by a conformal transformation. More formally, let (M, g) be a pseudo Riemannian manifold. Then (M, g) is conformally flat if for… …
9Green's function for the three-variable Laplace equation — The free space Green s function for the three variable Laplace equation is given in terms of the reciprocal distance between two points. That is to say the solution of the equation : abla^2 G(mathbf{x},mathbf{x }) = delta(mathbf{x} mathbf{x }) is …
10Surjective function — Onto redirects here. For other uses, see wikt:onto. A surjective function from domain X to codomain Y. The function is surjective because every point in the codomain is the value of f(x) for at least one point x in the domain. In mathematics, a… …
