I need this library in JS or Python #35
Comments
|
1. I reviewed the pywt library for a technical Journal a few years ago but
I haven't looked at it recently so I can't really comment . However, I
think you should be able to get more than 2 decomposition levels for a
75000 datapoint signal.
2. Javascript code is the emscripten/WASM code so it is a lot more
efficient than a plain js code. You can check
https://github.com/rafat/wavelib/blob/gh-pages/js/ngfile.js to see how to
call the dwt/swt functions in javascript.

I have played around with the Python package:

a decomposing level of max 2 when my input array is of 75000 data-points?
In your smaller online demo here:
https://rafat.github.io/wavelib/#/denoise I can set the following:
VisuShrink, biorthogonal, SWT, hard, bior1.1 AND a lot higher decomposing
level of 11?? Why is this possible when the python library only support
level 2 in my case?
2.
I need this wavelib library in javascript (or python): I can see in
the source code of the demo page that a js-file exists - but it looks like
it is obfuscated or similar?
https://rafat.github.io/wavelib/js/wavelib.js Does an JS version of
the library exist?
I'm all new to wavelets - so sorry if I ask about something obvious to you
guys :)
Thank you so much!

1. Yes I have now realized that the SWT function has a very specific need
in regards to the length of the
input array. When I adjust the length I can get 10-15 in decomposing levels.
2. I have tried to download the entire repo but I can't run it locally on
my Windows pc. I mean, I can open the HTML files
in the browser. But nothing happens when I click on any of the UI
components? What am I missing here?
3. Should this wavelib repo generate the exact same result as the Python
PyWavelets module?
4. Do you have time to help me with a pure javascript / nodejs solution if
I pay you? I don't need any UI.
I only need to be able to denoise 1d decimal arrays with the different
wavelet settings as shown in the wavelib demo.
Thank you so much in advance!

The best solution will be for you to compile the c library to wasm
yourself. Coding the whole thing to JavaScript is going to take up a lot of
time unless you want only very specific functionality.

I think I’ll be able to help you with generating the wasm code and I don’t
think it’ll take too long. About pywavelets, the only way to find out is by
testing a signal against both this library and pywavelets. I think we are
using the same filters but the paddings may not be identical so the outputs
may not always be completely identical in every instance.

I see... But I have no experience with that and I guess all the
configuration would require a lot of knowledge about this library here and
it would be very time consuming as well?
2.
Please answer this as well: Should this wavelib repo generate the
exact same result as the Python
PyWavelets module's functions? or is it better for me to use
PyWavelets and interact with it via a websocket/api?
