tensorflow-mri - TensorFlow MRI 0.21.0

Release 0.21.0

This release contains new functionality for wavelet decomposition and reconstruction and optimized Gram matrices for some linear operators. It also redesigns the convex optimization module and contains some improvements to the documentation.

Breaking Changes

• tfmri.convex:

  • Argument ndim has been removed from all functions.
  • All functions will now require the domain dimension to be specified. Therefore, domain_dimension is now the first positional argument in several functions including ConvexFunctionIndicatorBall, ConvexFunctionNorm and ConvexFunctionTotalVariation. However, while this parameter is no longer optional, it is now possible to pass dynamic or static information as opposed to static only (at least in the general case, but specific operators may have additional restrictions).
  • For consistency and accuracy, argument axis of ConvexFunctionTotalVariation has been renamed to axes.

Major Features and Improvements

• tfmri.convex:

  • Added new class ConvexFunctionL1Wavelet, which enables image/signal reconstruction with L1-wavelet regularization.
  • Added new argument gram_operator to ConvexFunctionLeastSquares, which allows the user to specify a custom, potentially more efficient Gram matrix.

• tfmri.linalg:

  • Added new classes LinearOperatorNUFFT and LinearOperatorGramNUFFT to enable the use of NUFFT as a linear operator.
  • Added new class LinearOperatorWavelet to enable the use of wavelets as a linear operator.

• tfmri.sampling:

  • Added new ordering type sorted_half to radial_trajectory.

• tfmri.signal:

  • Added new functions wavedec and waverec for wavelet decomposition and reconstruction, as well as utilities wavelet_coeffs_to_tensor, tensor_to_wavelet_coeffs, and max_wavelet_level.

Bug Fixes and Other Changes

• tfmri.recon:

  • Improved error reporting for least_squares.

tensorflow-mri - TensorFlow MRI 0.20.0

Release 0.20.0

Major Features and Improvements

• tfmri.layers:

  • Added new layers MaxPooling1D, MaxPooling2D, MaxPooling3D, AveragePooling1D, AveragePooling2D and AveragePooling3D. These are drop-in replacements for the core Keras layers of the same name, but they also support complex values.
  • Added new layers DWT1D, DWT2D, DWT3D, IDWT1D, IDWT2D, and IDWT3D to compute 1D, 2D and 3D forward and inverse discrete wavelet transforms.
  • Layer ConvBlock is now deprecated in favor of the new endpoints in the tfmri.models submodule.
  • Layer UNet is now deprecated in favor of the new endpoints in the tfmri.models submodule.

• tfmri.models:

  • Added new models ConvBlock1D, ConvBlock2D and ConvBlock3D. These replace the previous ConvBlock layer, which is now deprecated.
  • Added new models UNet1D, UNet2D and UNet3D. These replace the previous UNet layer, which is now deprecated.

Bug Fixes and Other Changes

• tfmri.signal:

  • Improved static shape inference for dwt op.

tensorflow-mri - TensorFlow MRI 0.19.0

Release 0.19.0

This release bumps the supported TensorFlow version to 2.9.

Major Features and Improvements

• tfmri.image:

  • Added new arguments batch_dims and image_dims to image_gradients, gradient_magnitude, psnr, ssim and ssim_multiscale.
  • Argument rank of psnr, ssim and ssim_multiscale is now deprecated. To update, use image_dims instead.
  • image_gradients and gradient_magnitude now support complex inputs.

• tfmri.losses:

  • Added new arguments batch_dims and image_dims to all image quality losses. Argument rank is now deprecated (use image_dims instead).
  • Added new arguments multichannel and complex_part to all image quality losses. These mirror the behaviour of the corresponding metrics and allows for single-channel inputs and extraction of parts from complex numbers, respectively.
  • The canonical API names StructuralSimilarityLoss and MultiscaleStructuralSimilarityLoss have been changed to SSIMLoss and SSIMMultiscaleLoss, respectively. The old names are still available, but may be removed in the future.

• tfmri.metrics:

  • Image quality metrics can now accept complex inputs without also specifying complex_part, in which case the unmodified complex values will be passed to the downstream function. This may not be supported for all metrics.
  • Added new arguments batch_dims and image_dims to all image quality metrics. Argument rank is now deprecated (use image_dims instead).
  • The canonical API names PeakSignalToNoiseRatio, StructuralSimilarity and MultiscaleStructuralSimilarity have been changed to PSNR, SSIM and SSIMMultiscale, respectively. The old names are still available, but may be removed in the future.

• tfmri.recon:

  • Added new argument preserve_phase to tfmri.recon.pf. This allows the user to recover the phase as well as the magnitude during partial Fourier reconstruction. Argument return_complex has the same behaviour and is now deprecated.
  • Added new aliases adjoint (for adj), least_squares (for lstsq) and partial_fourier (for pf). These are now the canonical aliases, but the old ones will still be supported.

• tfmri.signal:

  • Added new ops dwt and idwt to compute the N-dimensional discrete wavelet transform and its inverse, respectively.

• tfmri.plot:

  • Added new argument norm to image_sequence, tiled_image and tiled_image_sequence. This allows the user to specify the scaling to be applied before the colormap.

Bug Fixes and Other Changes

• Fixed a bug with k-space weighting in homodyne detection method of tfmri.recon.partial_fourier.
• Like core TensorFlow, we now compile with _GLIBCXX_USE_CXX11_ABI=1.
• Like core TensorFlow, Python wheels now conform to manylinux2014, an upgrade from manylinux2010.

• tfmri.initializers:

  • New module with initializers VarianceScaling, GlorotNormal, GlorotUniform, HeNormal, HeUniform, LecunNormal and LecunUniform. All initializers are drop-in replacements for their Keras counterparts and support complex values.
