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 — is the procedure of constraining something from a continuous set of values (such as the real numbers) to a discrete set (such as the integers). Quantization in specific domains is discussed in:* Quantization (signal processing) ** Quantization… … Wikipedia
Image compression — is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.Image compression can be lossy or lossless. Lossless… … Wikipedia
Image processing — is any form of signal processing for which the input is an image, such as photographs or frames of video; the output of image processing can be either an image or a set of characteristics or parameters related to the image. Most image processing… … 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
Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… … Wikipedia
Image-Pngslimmer — is a perl module of functions to reduce the size of PNG computer graphics. It can be found on CPAN [http://search.cpan.org/ acmcmen/Image Pngslimmer 0.22/lib/Image/Pngslimmer.pm] or at the author s own subversion repository… … Wikipedia
quantization — ● ►en n. f. ►AFFICH Opération consistant à réduire le nombre des couleurs d une image de 16 millions à 256 (par exemple), en essayant d obtenir une palette finale globalement proche des couleurs d origine.

Color quantization — An example image in 24 bit RGB color The same image reduced to a palette of 16 colors specifically chosen to best represent the image; the selected palette is shown by the squares above In … Wikipedia
BRST quantization — In theoretical physics, BRST quantization (where the BRST refers to Becchi, Rouet, Stora and Tyutin) is a relatively rigorous mathematical approach to quantizing a field theory with a gauge symmetry. Quantization rules in earlier QFT frameworks… … Wikipedia
