For certain signal processing
I want to do discrete wavelet transform in python.
I checked it, but I couldn't find an article that could be used as a reference.
If anyone has any implementation experience, please help.
I'd be happy if you could give me some tips on the site, python packages, etc.
TriedIf it is a continuous wavelet transform, pywavelets looks pretty much like that ...
Supplemental information (FW/tool version etc.)Any python version etc. doesn't matter.
Should I do it with matlab?

If you want to create multiresolution images, you might want to take a look at OpenCV. Although it is not a disassembly for each direction like JPEG2000.
