The Wavelet Properties Browser on [wavelets.pybytes.com](wavelets.pybytes.com) is supposed to show illustrations (images) of each wavelet family, but none of the images appear. This problem occurs on every "wavelet family" page;...

question

Hello! I noticed that the PSD calculated using `pywt.cwt` with the `cmor2.5-1` wavelet is lower than the results obtained using `scipy.signal.welch` and `pycwt.cwt` with the `morlet` wavelet. Due to my...

question

In the second plot, updated Fs to 512; `ax2.specgram(data, NFFT=64, noverlap=32, Fs=512, cmap=cmap, interpolation='bilinear')` again in the second plot, added aspect='auto', and did corrections to the time (x axis) and...

When I use the pywt.swt function for a level 1 transform I get different results than when doing a manual convolution with the low pass and high pass filters using...

question

Is there a way to do a non-decimated wavelet packet transform using PyWavelets?

question

Hi PyWavelets team, I'm trying to locate the exact place in the codebase where the filter coefficients (e.g., for db3) are defined. I'm aware that they can be accessed at...

Generating a scalogram from the full output of the Continuous Wavelet Transform (CWT) entails high computational cost while providing limited performance gains in acoustic recognition models based on deep learning....

I run the following code to visualize some wavelets with specific wavelengths. However when I increase my wavelength some samples will spike towards 0. This gets increasingly worse with longer...

bug

Hello @rgommers , I had many issues in controlling the precision of the wavelet (`def wavefun()`). This issue has been mentioned several times already, but never committed. I think this...

I saw linear `scales` in some important code recently (written by those who don't know better). There will almost never be a use case for this. CWT is a log...
