Subband coding resides at the heart of the popular MP3 format (more properly known as MPEG-1 Audio Layer III), for example. Sub-band coding is used in the G.722 codec which uses sub-band adaptive differential pulse code modulation (SB-ADPCM) within a bit rate of 64 kbit/s. In the SB-ADPCM technique, the frequency band is split into two sub ...
Originally known as optimal subband tree structuring (SB-TS), also called wavelet packet decomposition (WPD; sometimes known as just wavelet packets or subband tree), is a wavelet transform where the discrete-time (sampled) signal is passed through more filters than the discrete wavelet transform (DWT).
Martin Vetterli is a co-author of the book Wavelets and Subband Coding (Prentice-Hall, 1995). [9] In 2008, Vetterli authored with Paolo Prandoni a free textbook Signal Processing for Communications. [10]

The stationary wavelet transform (SWT) [1] is a wavelet transform algorithm designed to overcome the lack of translation-invariance of the discrete wavelet transform (DWT). ). Translation-invariance is achieved by removing the downsamplers and upsamplers in the DWT and upsampling the filter coefficients by a factor of () in the th level of the alg
Embedded zerotree wavelet algorithm (EZW) as developed by J. Shapiro in 1993, enables scalable image transmission and decoding. It is based on four key concepts: first, it should be a discrete wavelet transform or hierarchical subband decomposition; second, it should predict the absence of significant information when exploring the self-similarity inherent in images; third, it has entropy ...

Ali Naci Akansu (born May 6, 1958) is a Turkish-American professor of electrical & computer engineering and scientist in applied mathematics.. He is best known for his contributions to the theory and applications of linear subspace methods including sub-band and wavelet transforms, particularly the binomial QMF [1] [2] (also known as Daubechies wavelet) and the multivariate framework to design ...
