Quantization (physics)
PROCEDURE TO CONSTRUCT A QUANTUM SYSTEM WHOSE CLASSICAL LIMIT CORRESPONDS TO A GIVEN CLASSICAL SYSTEM
Field quanta; Energy quantization; Quantisation (physics); Field quantum
In physics, quantization (in British English quantisation) is the systematic transition procedure from a classical understanding of physical phenomena to a newer understanding known as quantum mechanics. It is a procedure for constructing quantum mechanics from classical mechanics.
Quantization (signal processing)
PROCESS OF MAPPING A CONTINUOUS SET TO A COUNTABLE SET
Quantisation (signal processing); Quantization noise; Quantisation noise; Quantization error; 8-bit sample; Quantizing noise; Quantisation error; Quantization (sound processing); Adaptive Quantization; Quantized signal; Scalar quantization; Quantization distortion; Q-noise; Quantizer; Quantiser; Signal quantization; Quantization error model; Dead-zone quantizer; Draft:Quantizationerror draft
Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. Rounding and truncation are typical examples of quantization processes.

Quantization
Quantization is the process of constraining an input from a continuous or otherwise large set of values (such as the real numbers) to a discrete set (such as the integers). The term quantization may refer to:
First quantization
First quantisation; Semi-classical theory
A first quantization of a physical system is a possibly semiclassical treatment of quantum mechanics, in which particles or physical objects are treated using quantum wave functions but the surrounding environment (for example a potential well or a bulk electromagnetic field or gravitational field) is treated classically.
Second quantization
FORMULATION OF THE QUANTUM MANY-BODY PROBLEM
Field Quantization; Second quantisation; Occupation number representation; 2nd quantization
Second quantization, also referred to as occupation number representation, is a formalism used to describe and analyze quantum many-body systems. In quantum field theory, it is known as canonical quantization, in which the fields (typically as the wave functions of matter) are thought of as field operators, in a manner similar to how the physical quantities (position, momentum, etc.
Trellis quantization
METHOD OF IMPROVING DATA COMPRESSION, OFTEN USED IN LOSSY VIDEO COMPRESSION
Trellis quantisation
Trellis quantization is an algorithm that can improve data compression in DCT-based encoding methods. It is used to optimize residual DCT coefficients after motion estimation in lossy video compression encoders such as Xvid and x264.
Geometric quantization
MATHEMATICAL APPROACH TO DEFINING A QUANTUM THEORY CORRESPONDING TO A GIVEN CLASSICAL THEORY
Geometric quantisation; Prequantization
In mathematical physics, geometric quantization is a mathematical approach to defining a quantum theory corresponding to a given classical theory. It attempts to carry out quantization, for which there is in general no exact recipe, in such a way that certain analogies between the classical theory and the quantum theory remain manifest.

Color image quantization; Colour quantisation; Colour image quantisation; Colour quantization
In computer graphics, color quantization or color image quantization is quantization applied to color spaces; it is a process that reduces the number of distinct colors used in an image, usually with the intention that the new image should be as visually similar as possible to the original image. Computer algorithms to perform color quantization on bitmaps have been studied since the 1970s.
Quantization (image processing)
COMPRESSION TECHNIQUE INVOLVED IN IMAGE PROCESSING
Quantization matrix; Quantization matrices; Image quantization; Quantisation matrix; Quantisation matrices
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 compressible.
