13Audio Lossless Coding — MPEG 4 Audio Lossless Coding, auch bekannt unter MPEG 4 ALS, ist eine Erweiterung zum MPEG 4 Audio Standard um verlustfreie Audiodatenkompression zu ermöglichen. Die Entwicklung dieser Erweiterung wurde im Dezember 2005 abgeschlossen.… …
14Huffman coding — Huffman tree generated from the exact frequencies of the text this is an example of a huffman tree . The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 bits, as opposed of 288 bits if 36… …
15Discrete cosine transform — A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy… …
16Discrete Fourier transform (general) — See also: Fourier transform on finite groups This article is about the discrete Fourier transform (DFT) over any field (including finite fields), commonly called a number theoretic transform (NTT) in the case of finite fields. For specific… …
17Continuous wavelet transform — of frequency breakdown signal. Used symlet with 5 vanishing moments. A continuous wavelet transform (CWT) is used to divide a continuous time function into wavelets. Unlike Fourier transform, the continuous wavelet transform possesses the ability …
18Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… …
19Common coding theory — is a cognitive psychology theory describing how perceptual representations (e.g. of things we can see and hear) and motor representations (e.g. of hand actions) are linked. The theory claims that there is a shared representation (a common code)… …
20Extract, transform, load — Extract, transform and load (ETL) is a process in database usage and especially in data warehousing that involves: Extracting data from outside sources Transforming it to fit operational needs (which can include quality levels) Loading it into… …
