Pywt.upcoef can implement a layer of decomposition and reconstruction of wavelets in Python, but after multi-layer decomposition, it is wrong to reconstruct data.

I'd like to use [generalized Morse wavelets](https://doi.org/10.1109/TSP.2012.2210890) for an analysis and am under the impression that it is not implemented in pywt.
These wavelets are defined by i…

dear Colin M McCrimmon:
Recently, I saw your program when I was reading the paper. I find your research is very valuable and meaningful. Unfortunately, I can't understand the meaning of the stateme…

One of the issues with Fourier is over sampling in the lower frequency domains.
An alternative might be wavelets, which would handle over sampling in the low frequency area, and would give you the ch…

Hi,
I ran a CWT using ContinuousWavelets, Matlab WTC package (Grinstead), and R's Biwavelet package, on the same signal.
The result are consistent between R and matlab, but not at all with Continu…

Hello everyone! In the version of Matlab R2016a I did some work implementing the daubechies wavelet in the continuous wavelet transform, CWT. I need to replicate these results in Python. Searching dif…

Would be more accurate and able to recognize different waveforms.
Long-term, because it is not very necessary and would mean a big overhaul

Original issue reported on code.google.com by `koo…

It would be great to propose several sets of wavelets. Gabor are real in fourier, thus adding Haar wavelets (despite being simple and having a different structure) could make a lot of sens w.r.t. the …

Erik mentioned a nice idea with regards to performing PE with multiple wavelets:
Namely, we iteratively perform PE, subtract the estimated wavelet, and re-perform PE until some criterion is met.

Kymatio and scatnet apply a "periodization" to the wavelets, ref:
