ptwt - ptwt v0.1.7

What's New

  • pywt compatible axis and axes argument support along with tests.

Breaking changes:

  • The new axis or axes argument appears before arguments related to boundary wavelet support. Pywt does not support boundary wavelets, so to respect pywt argument order we have added the new arguments before anything related to boundary wavelets. This makes it easy to migrate from pywt to ptwt and back. Unfortunately, this choice breaks calls to boundary wavelet arguments which follow the old order. To migrate, call arguments related to boundary wavelets by name. This affects only matrix-fwt and wavelet-packet code that uses boundary wavelet support.

What's Changed

  • V0lta docs patch by @v0lta in https://github.com/v0lta/PyTorch-Wavelet-Toolbox/pull/64
  • test update. by @v0lta in https://github.com/v0lta/PyTorch-Wavelet-Toolbox/pull/65
  • Axis support by @loki-veera in https://github.com/v0lta/PyTorch-Wavelet-Toolbox/pull/67

- Python
Published by v0lta over 2 years ago

ptwt - ptwt v.0.1.6

What's new:

  • support for symmetric padding for all convolution-based transformations (the default in pywt).
  • channel dimensions are now automatically processed along with batch dimensions for 1d and 2d code for easier integration into machine learning models.

What's Changed

  • Speed tests by @v0lta in https://github.com/v0lta/PyTorch-Wavelet-Toolbox/pull/55
  • Update readme.md by @v0lta in https://github.com/v0lta/PyTorch-Wavelet-Toolbox/pull/56

ptwt - ptwt v.0.1.5

What's Changed

  • added additional test cases for our wavedec3 and 1D-matrix transformation code.
    • 3d matrix transformation support. The new matrix-wavedecs3 returns a list of dictionaries like https://pywavelets.readthedocs.io/en/latest/ref/nd-dwt-and-idwt.html#multilevel-decomposition-wavedecn .
    • The separable_conv_transform module now provides support for separable padded transforms.
  • improved handling of the internal "channel"-dimension for the padded 2d-fwt case. Output tensors from wavedec2 now have the shape [batch, height, width] instead of [batch, 1, height, width].
  • Added shape checks for the transformed coefficients, for more informative error messages.
  • Added tests for just in time compilation. See test/test_jit.py for more details.

Breaking changes

  • since https://arxiv.org/pdf/2210.14874.pdf found them to work well, the faster separable transforms are now the default for all boundary wavelet computations. If you require wavedec2 and MatrixWavedec2 to produce identical coefficients in the Haar case, set separable to False.
  • to simplify the documentation _get_pad is now private.
  • To ensure our API is compatible with pywt the padded analysis transforms argument order has changed. The order is now always data, wavelet, mode, level.

ptwt - ptwt v0.1.1

What's new: - Features: - wavedec and wavedec2 now additionally support constant and periodic padding. - Further expanded the test coverage. - Added Python 3.10.2 support. - Moved the CI-Pipeline from tox to nox ( https://nox.thea.codes/en/stable/index.html ).

  • Bugfixes:

    • Fixed a bug in the 2d-boundary-wavelet code. Using non-separated two-dimensional boundary wavelets on non-square images now works as expected. We thank @raoulheese for reporting this one!

  • Breaking changes:

    • Removed the redundant level argument from the fwt_pad2 function.
