• Quantization (image processing) — Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum value. When the number of discrete symbols in a given stream is reduced, the stream becomes more… …   Wikipedia

• Quantization error — The difference between the actual analog value and quantized digital value due is called quantization error. This error is due either to rounding or truncation.Many physical quantities are actually quantized by physical entities. Examples of… …   Wikipedia

• Quantization (signal processing) — In digital signal processing, quantization is the process of approximating a continuous range of values (or a very large set of possible discrete values) by a relatively small set of discrete symbols or integer values.More specifically, a signal… …   Wikipedia

• Vector quantization — is a classical quantization technique from signal processing which allows the modeling of probability density functions by the distribution of prototype vectors. It was originally used for data compression. It works by dividing a large set of… …   Wikipedia

• Redshift quantization — is the hypothesis that the redshifts of cosmologically distant objects (in particular galaxies) tend to cluster around multiples of some particular value. Since there is a correlation of distance and redshift as expressed in Hubble s Law,… …   Wikipedia

• Canonical quantization — In physics, canonical quantization is one of many procedures for quantizing a classical theory. Historically, this was the earliest method to be used to build quantum mechanics. When applied to a classical field theory it is also called second… …   Wikipedia

• Weyl quantization — In mathematics and physics, in the area of quantum mechanics, Weyl quantization is a method for systematically associating a quantum mechanical Hermitian operator with a classical kernel function in phase space invertibly. A synonym is phase… …   Wikipedia

• Light front quantization — In theoretical physics, light front quantization refers to a specific choice of the initial degrees of freedom i.e. canonical coordinates and their momenta. While the usual option in field theory is to determine their value at a particular value… …   Wikipedia

• Landau quantization — in quantum mechanics is the quantization of the cyclotron orbits of charged particles in magnetic fields. As a result, the charged particles can only occupy orbits with discrete energy values, called Landau levels. The Landau levels are… …   Wikipedia

• Mean square quantization error — (MSQE) is a figure of merit for the process of analog to digital conversion. As the input is varied, the input s value is recorded when the digital output changes. For each digital output, the input s difference from ideal is normalized to the… …   Wikipedia

• Flux quantization — is a quantum phenomenon in which the magnetic field is quantized in the unit of h / 2e,also known variously as flux quanta, fluxoids, vortices or fluxons.Flux quantization occurs in Type II superconductors subjected to a magnetic field. Below a… …   Wikipedia
