2. Morlet wavelet - Wikipedia

   en.wikipedia.org/wiki/Morlet_wavelet

   The Morlet wavelet transform is capable of capturing short bursts of repeating and alternating music notes with a clear start and end time for each note. [citation needed] A modified morlet wavelet was proposed to extract melody from polyphonic music. [11] This methodology is designed for the detection of closed frequency.

3. Continuous wavelet - Wikipedia

   en.wikipedia.org/wiki/Continuous_wavelet

   Most of the continuous wavelets are used for both wavelet decomposition and composition transforms. That is they are the continuous counterpart of orthogonal wavelets. [1] [2] The following continuous wavelets have been invented for various applications: [3] Poisson wavelet; Morlet wavelet; Modified Morlet wavelet; Mexican hat wavelet

4. Constant-Q transform - Wikipedia

   en.wikipedia.org/wiki/Constant-Q_transform

   It is related to the Fourier transform [1] and very closely related to the complex Morlet wavelet transform. [2] Its design is suited for musical representation. Constant-Q transform applied to the waveform of a C major piano chord. The x-axis is frequency, mapped to standard musical pitches, from low (left) to high (right). The y-axis is time ...

5. Modified Morlet wavelet - Wikipedia

   en.wikipedia.org/wiki/Modified_Morlet_wavelet

   Modified Mexican hat, Modified Morlet and Dark soliton or Darklet wavelets are derived from hyperbolic (sech) (bright soliton) and hyperbolic tangent (tanh) (dark soliton) pulses. These functions are derived intuitively from the solutions of the nonlinear Schrödinger equation in the anomalous and normal dispersion regimes in a similar fashion ...

6. Continuous wavelet transform - Wikipedia

   en.wikipedia.org/wiki/Continuous_wavelet_transform

   Continuous wavelet transform of frequency breakdown signal. Used symlet with 5 vanishing moments.. In mathematics, the continuous wavelet transform (CWT) is a formal (i.e., non-numerical) tool that provides an overcomplete representation of a signal by letting the translation and scale parameter of the wavelets vary continuously.

   Wavelet compression is a form of data compression well suited for image compression (sometimes also video compression and audio compression). Notable implementations are JPEG 2000 , DjVu and ECW for still images, JPEG XS , CineForm , and the BBC's Dirac .
