Announcement: scikit-image 0.14.1
=================================

We're happy to announce the release of scikit-image v0.14.1!

scikit-image is an image processing toolbox for SciPy that includes algorithms
for segmentation, geometric transformations, color space manipulation,
analysis, filtering, morphology, feature detection, and more.

This is our first release under our Long Term Support for 0.14 policy. As a
reminder, 0.14 is the last release to support Python 2.7, but it will be
updated with bug fixes and popular features until January 1st, 2020.

This release contains the following changes from 0.14.0:


Bug fixes

------------
- "Reflect" mode in transforms now works fine when an image dimension has size
  1 (#3174)
- ``img_as_float`` now allows single-precision (32-bit) float arrays to pass
  through unmodified, rather than being up-converted to 64-bit (#3110, #3052,
  #3391)
- Speed up rgb2gray computation (#3187)
- The scikit-image viewer now works with different PyQt versions (#3157)
- The ``cycle_spin`` function for enhanced denoising works single-threaded
  when dask is not installed now (#3218)

Announcement: scikit-image 0.14.0
=================================

We're happy to announce the release of scikit-image v0.14.0!

scikit-image is an image processing toolbox for SciPy that includes algorithms
for segmentation, geometric transformations, color space manipulation,
analysis, filtering, morphology, feature detection, and more.

This is the last major release with official support for Python 2.7. Future
releases will be developed using Python 3-only syntax.

However, 0.14 is a long-term support (LTS) release and will receive bug fixes
and backported features deemed important (by community demand) until January
1st 2020 (end of maintenance for Python 2.7; see PEP 373 for details).

For more information, examples, and documentation, please visit our website:

http://scikit-image.org


New Features
------------
- Lookfor function to search across the library: ``skimage.lookfor``. (#2713)
- nD support for ``skimage.transform.rescale``, ``skimage.transform.resize``,
  and ``skimage.transform.pyramid_*`` transforms. (#1522)
- Chan-Vese segmentation algorithm. (#1957)
- Manual segmentation with matplotlib for fast data annotation:
  ``skimage.future.manual_polygon_segmentation``,
  ``skimage.future.manual_lasso_segmentation``. (#2584)
- Hysteresis thresholding:
  ``skimage.filters.apply_hysteresis_threshold``. (#2665)
- Segmentation with morphological snakes:
  ``skimage.segmentation.morphological_chan_vese`` (2D),
  ``skimage.segmentation.morphological_geodesic_active_contour`` (2D and 3D). (#2791)
- nD support for image moments: ``skimage.measure.moments_central``,
  ``skimage.measure.moments_central``, ``skimage.measure.moments_normalized``,
  ``skimage.measure.moments_hu``. This change leads to 3D/nD compatibility for
  many regionprops. (#2603)
- Image moments from coordinate input: ``skimage.measure.moments_coords``,
  ``skimage.measure.moments_coords_central``. (#2859)
- Added 3D support to ``blob_dog`` and ``blob_log``. (#2854)
- Inertia tensor and its eigenvalues can now be computed outside of
  regionprops; available in ``skimage.measure.inertia_tensor``. (#2603)
- Cycle-spinning function for approximating shift-invariance by averaging
  results from a series of spatial shifts:
  ``skimage.restoration.cycle_spin``. (#2647)
- Haar-like feature: ``skimage.feature.haar_like_feature``,
  ``skimage.feature.haar_like_feature_coord``,
  ``skimage.feature.draw_haar_like_feature``. (#2848)
- Data generation with random_shapes function:
  ``skimage.draw.random_shapes``. (#2773)
- Subset of LFW (Labeled Faces in the Wild) database:
  ``skimage.data.cbcl_face_database``. (#2905)
- Fully reworked montage function (now with a better padding behavior):
  ``skimage.util.montage``. (#2626)
- YDbDr colorspace conversion routines: ``skimage.color.rgb2ydbdr``,
  ``skimage.color.ydbdr2rgb``. (#3018)


Improvements
------------
- ``VisuShrink`` method for ``skimage.restoration.denoise_wavelet``. (#2470)
- New ``max_ratio`` parameter for ``skimage.feature.match_descriptors``. (#2472)
- ``skimage.transform.resize`` and ``skimage.transform.rescale`` have a new
  ``anti_aliasing`` option to avoid aliasing artifacts when down-sampling
  images. (#2802)
- Support for multichannel images for ``skimage.feature.hog``. (#2870)
- Non-local means denoising (``skimage.restoration.denoise_nl_means``) has
  a new optional parameter, ``sigma``, that can be used to specify the noise
  standard deviation. This enables noise-robust patch distance estimation. (#2890)
- Mixed dtypes support for ``skimage.measure.compare_ssim``,
  ``skimage.measure.compare_psnr``, etc. (#2893)
- New ``alignment`` parameter in ``skimage.feature.plot_matches``. (#2955)
- New ``seed`` parameter in ``skimage.transform.probabilistic_hough_line``. (#2960)
- Various performance improvements. (#2821, #2878, #2967, #3035, #3056, #3100)


Bugfixes
--------
- Fixed ``skimage.measure.regionprops.bbox_area`` returning incorrect value. (#2837)
- Changed gradient and L2-Hys norm computation in ``skimage.feature.hog``
  to closely follow the paper. (#2864)
- Fixed ``skimage.color.convert_colorspace`` not working for YCbCr, YPbPr. (#2780)
- Fixed incorrect composition of projective tranformation with inverse transformation. (#2826)
- Fixed bug in random walker appearing when seed pixels are isolated inside pruned zones. (#2946)
- Fixed ``rescale`` not working properly with different rescale factors in multichannel case. (#2959)
- Fixed float and integer dtype support in ``skimage.util.invert``. (#3030)
- Fixed ``skimage.measure.find_contours`` raising StopIteration on Python 3.7. (#3038)
- Fixed platform-specific issues appearing in Windows and/or 32-bit environments. (#2867, #3033)


API Changes
-----------
- ``skimage.util.montage.`` namespace has been removed, and
  ``skimage.util.montage.montage2d`` function is now available as
  ``skimage.util.montage2d``.
- ``skimage.morphology.binary_erosion`` now uses ``True`` as border
  value, and is now consistent with ``skimage.morphology.erosion``.


Deprecations
------------
- ``freeimage`` plugin has been removed from ``skimage.io``.
- ``skimage.util.montage2d`` is deprecated and will be removed in 0.15.
  Use ``skimage.util.montage`` function instead.
- ``skimage.novice`` is deprecated and will be removed in 0.16.
- ``skimage.transform.resize`` and ``skimage.transform.rescale`` have a new
  ``anti_aliasing`` option that avoids aliasing artifacts when down-sampling
  images. This option will be enabled by default in 0.15.
- ``regionprops`` will use row-column coordinates in 0.16. You can start
  using them now with ``regionprops(..., coordinates='rc')``. You can silence
  warning messages, and retain the old behavior, with
  ``regionprops(..., coordinates='xy')``. However, that option will go away
  in 0.16 and result in an error. This change has a number of consequences.
  Specifically, the "orientation" region property will measure the
  anticlockwise angle from a *vertical* line, i.e. from the vector (1, 0) in
  row-column coordinates.
- ``skimage.morphology.remove_small_holes`` ``min_size`` argument is deprecated
  and will be removed in 0.16. Use ``area_threshold`` instead.
