0.4.8
- fix: cut-off radius too small in fmap_2d algorithm (#19)
0.4.7
- maintenance release
0.4.6
- fix: handle more special cases when computing weights for
projections
- docs: update example scripts and images
0.4.5
- ci: fix build pipeline
0.4.4
- ref: address scipy deprecation warnings
- ref: replace print statements with warnings (#17)
- ci: switch to Python 3.10
- ci: minor cleanup
0.4.3
- docs: added original meep C++ simulation files in "misc" (#14)
- docs: add ``if __name__ == "__main__"`` guard to 3D backpropagation
examples (#15)
0.4.2
- build: migrate to GitHub Actions
- build: setup.py test is deprecated
- docs: refurbish docs
- ref: change instances of np.int to int due to
numpy deprecation warnings
0.4.1
- setup: bump scipy to 1.4.0 (updated QHull in griddata)
0.4.0
- BREAKING CHANGES:
- renamed submodule `_preproc` to `_prepare_sino`
- renamed submodule `_postproc` to `_translate_ri`
- missing apple core correction is now applied to the
object function (`f`) instead of the refractive index (`n`),
which is the physically correct approach
- default keyword for `padval` is now "edge"
instead of `None`; the meaning is retained
- enh: added symmetric histogram apple core correction method "sh"
- fix: using "float32" dtype in 3D backpropagation lead to
casting error in numexpr
- enh: improve performance when padding is disabled
- docs: minor update
0.3.0
- feat: basic missing apple core correction (#6)
- docs: reordered 3D examples (decreasing importance)
0.2.6
- fix: make phase unwrapping deterministic
- tests: remove one test of the 2D Fourier mapping algorithm due to
instabilities in using scipy.interpolate.griddata
- ref: use `empty_aligned` instead of deprecated `n_byte_align_empty`
- docs: add hint for windows users how to run the 3D examples
0.2.5
- fix: reconstruction volume rotated by 180° due to floating point
inaccuracies (affects `backpropagate_3d_tilted`).
0.2.4
- maintenance release
0.2.3
- enh: employ slice-wise padding to reduce the memory usage (and
possibly the computation time) of
- basic 3D backpropagation algorithm (#7)
- 3D backpropagation with a tilted axis of rotation (#9)
- ref: replace asserts with raises (#8)
- ref: multiprocessing-based rotation does not anymore require
a variable (_shared_array) at the top level of the module; As a
result, multiprocessing-rotation should now also work on Windows.
0.2.2
- docs: minor update and add changelog
0.2.1
- fix: Allow sinogram data type other than complex128
- docs: Add example with experimental data (#3)
- ci: automated deployment with travis-ci
0.2.0
- BREAKING CHANGES:
- Dropped support for Python 2
- Renamed `sum_2d` to `integrate_2d`
- Refactoring (#4, #5):
- Moved each reconstruction algorithm to a separate file
- Modified code to comply with PEP8
- Moved long doc strings from source to docs directory
- Migrate from unwrap to scikit-image
- Cleaned up example scripts
- Bugfixes:
- Mistake in "negative-modulo" method for determination of
2PI sinogram phase offsets
0.1.8
- Updated documentation
- Cleaned up examples
0.1.7
- Move documentation from GitHub to readthedocs.io
- Add universal wheel on PyPI
- Update tests on travis with new versions of NumPy
0.1.6
- Bugfixes:
- size of reconstruction volume in z too large for cases where
the y-size is larger than the x-size of the sinogram images
- `backpropagate_3d_tilted` used wrong shape of projections
- 3D backpropagation methods did not use power-of-two padding size
0.1.5
- Code optimization (speed, memory) with numexpr
- New keyword argument `save_memory` for 3D reconstruction
on machines with limited memory
- New keyword argument `copy` for 3D reconstruction to protect
input sinogram data.
0.1.4
- The exponential term containing the distance between center
of rotation and detector `lD` is now multiplied with
the factor `M-1` instead of `M`. This is necessary,
because usually the scattered wave is normalized in both
amplitude and phase (`u_0`) and not only amplitude `a_0`
- Allow angles of shape (A,1) in `backpropagate_3d_tilted`
- Set default value lD=0 for all reconstruction algorithms
- Improvement of documentation
0.1.3
- Fixes for `backpropagate_3d_tilted` when `angles` are
points on the unit sphere:
- Make sure each point is normalized
- Correctly rotate each point w.r.t. `tilted_axis`
0.1.2
- Added reconstruction algorithm for tilted axis of rotation
0.1.1
- Support NumPy 1.10.
- Allow to weight backpropagation using keyword `weight_angles`
- Bugfix: backpropagate_3d with keyword `onlyreal=True` did not work
- Bugfix: sum_2d did not return correctly shaped array
- Code coverage is now 90%
- Added more examples to the documentation
