  1. Wavelet Scattering explanation? - Signal Processing Stack Exchange

    Oct 2, 2021 · Wavelet Scattering is an equivalent deep convolutional network, formed by cascade of wavelets, modulus nonlinearities, and lowpass filters. It yields representations that are time …

  2. PyWavelets CWT implementation - Signal Processing Stack Exchange

    Sep 28, 2020 · I seek to understand PyWavelets' implementation of the Continuous Wavelet Transform, and how it compares to the more 'basic' version I've coded and provided here. In …

  3. What's the difference between the Gabor and Morlet wavelets?

    The Gabor wavelet is a kind of the Gaussian modulated sinusoidal wave (source)   Gabor wavelets are formed from two components, a complex sinusoidal carrier and a Gaussian …

  4. python - Feature extraction/reduction using DWT - Signal …

    For a given time series which is n timestamps in length, we can take Discrete Wavelet Transform (using 'Haar' wavelets), then we get (for an example, in Python) -

  5. Power/Energy from Continuous Wavelet Transform

    Jan 13, 2023 · How can power or energy be computed from Continuous Wavelet Transform? Is it just $\sum |\text {CWT} (x)|^2$, or are there other considerations, particularly if interested in a …

  6. Discrete wavelet transform; how to interpret approximation and …

    Discrete wavelet transform; how to interpret approximation and detail coefficients? Ask Question Asked 8 years ago Modified 2 years, 8 months ago

  7. What is the scaling function and wavelet function at wavelet …

    May 6, 2015 · I'm trying to looking the meaning and functionality about scaling function and wavelet function at wavelet analysis. I have googling already. But I can't find and understand …

  8. Wavelet thresholding - Signal Processing Stack Exchange

    What is the difference between soft thresholding and hard thresholding. Where we use soft and hard thresholding in image for denoising. I understand that in hard thresholding, the …

  9. Scalogram (and related nomenclatures) for DWT?

    Continuous wavelet transform is suitable for a scalogram because the analysis window can be sized and placed at any position. This flexibility allows for the generation of a smooth image in …

  10. wavelet - CWT at low scales: PyWavelets vs Scipy - Signal …

    Oct 6, 2020 · Low scales are arguably the most challenging to implement due to limitations in discretized representations. Detailed comparison here; the principal difference is in how the …
