  • 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 (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

  • Quantization (physics) — In physics, quantization is a procedure for constructing a quantum field theory starting from a classical field theory. This is a generalization of the procedure for building quantum mechanics from classical mechanics. One also speaks of field… …   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 (music) — Time quantization In digital music processing technology, quantization is the process of aligning a set of musical notes to a precise setting. This results in notes being set on beats and on exact fractions of beats. The most frequent application …   Wikipedia

  • Quantization (linguistics) — In linguistics, a quantized expression is such that, whenever it is true of some entity, it is not true of any proper subparts of that entity. Example: If something is an apple , then no proper subpart of that thing is an apple . If something is… …   Wikipedia
