I am +1 on @aaren's `TransformResult.array` method. I am not sure having a class is of much utility for a simple 1D DWT, but I guess if we go that...

I think the TransformResult object should also have a copy of the original shape prior to the transformation. This way problems like the example below could be automatically fixed by...

Hi @micha2718l. Over in #394, @rgommers suggested renaming to `estimate_noise` or `estimate_noiselevel`. I think `estimate_noise` sounds reasonable and may be clearer to users than `estimate_sigma`. What do you think?

I agree that FFT-based is not necessarily faster. In a particular case I looked at for DWTs in Matlab in the past, I think FFT-based was faster for filter lengths...

> I also learned from docs the MATLAB's cwt can give negative scales, though they don's show any exmaples about it. I'm wondering if cwt function can work with negative...

This was partially resolved by #635, which added `frequency2scale`

@kwohlfahrt: I know it has been a long time since this was originally asked, but the use of `waverecn` with `None` for the detail coefficients (and `[None, None]` for additional...

Hi @sarmientoj24, here are some ideas: For CLAHE, I would install [scikit-image](https://scikit-image.org) and then use [skimage.exposure.equalize_adapthist](https://scikit-image.org/docs/dev/api/skimage.exposure.html#equalize-adapthist). For `BayesShrink` there is an implementation in [skimage.restoration.denoise_wavelet](https://github.com/scikit-image/scikit-image/blob/ba987180c1c6145896c7f10b423199dc34888039/skimage/restoration/_denoise.py#L757-L760) that is based on PyWavelets. The...

This is a bit tricky, but let me try to explain what is going on. I think this is a subtlety that we have not documented well. The first point...
