scikit-image 0.12.3 (2016-03-08)
================================

We're happy to announce the release of scikit-image v0.12.3!

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.

Highlights and new features
---------------------------

For this release, we merged over 200 pull requests with bug fixes,
cleanups, improved documentation and new features.  Highlights
include:

- 3D skeletonization (#1923)
- Parallelization framework using ``dask``:``skimage.util.apply_parallel``
  (#1493)
- Laplacian operator ``filters.laplace`` (#1763)
- Synthetic 2-D and 3-D binary data with rounded blobs (#1485)
- Plugin for ``imageio`` library (#1575)
- Inpainting algorithm (#1804)
- New handling of background pixels for ``measure.label``: 0-valued
  pixels are considered as background by default, and the label of
  background pixels is 0.
- Partial support of 3-D images for ``skimage.measure.regionprops``
  (#1505)
- Multi-block local binary patterns (MB-LBP) for texture classification (#1536)
- Seam Carving (resizing without distortion) (#1459)
- Simple image comparison metrics (PSNR, NRMSE) (#1897)
- Region boundary based region adjacency graphs (RAG) (#1495)
- Construction of RAG from label images (#1826)
- ``morphology.remove_small_holes`` now complements
  ``morphology.remove_small_objects`` (#1689)
- Faster cython implementation of ``morphology.skeletonize``
- More appropriate default weights in
  ``restoration.denoise_tv_chambolle`` and ``feature.peak_local_max``
- Correction of bug in the computation of the Euler characteristic in
  ``measure.regionprops``.
- Replace jet by viridis as default colormap
- Alpha layer support for ``color.gray2rgb``
- The measure of structural similarity (``measure.compare_ssim``) is now
  n-dimensional and supports color channels as well.
- We fixed an issue related to incorrect propagation in plateaus in
  ``segmentation.watershed``

Documentation:

- New organization of gallery of examples in sections
- More frequent (automated) updates of online documentation

API Changes
-----------

- ``equalize_adapthist`` now takes a ``kernel_size`` keyword argument,
  replacing  the ``ntiles_*`` arguments.
- The functions ``blob_dog``, ``blob_log`` and ``blob_doh`` now return
  float  arrays instead of integer arrays.
- ``transform.integrate`` now takes lists of tuples instead of integers
  to define the window over which to integrate.
- `reverse_map` parameter in `skimage.transform.warp` has been removed.
- `enforce_connectivity` in `skimage.segmentation.slic` defaults to ``True``.
- `skimage.measure.fit.BaseModel._params`,
  `skimage.transform.ProjectiveTransform._matrix`,
  `skimage.transform.PolynomialTransform._params`,
  `skimage.transform.PiecewiseAffineTransform.affines_*` attributes
  have been removed.
- `skimage.filters.denoise_*` have moved to `skimage.restoration.denoise_*`.

Deprecations
------------

- ``filters.gaussian_filter`` has been renamed ``filters.gaussian``
- ``filters.gabor_filter`` has been renamed ``filters.gabor``
- ``restoration.nl_means_denoising`` has been renamed
  ``restoration.denoise_nl_means``
- ``measure.LineModel`` was deprecated in favor of ``measure.LineModelND``
- ``measure.structural_similarity`` has been renamed
  ``measure.compare_ssim``
- ``data.lena`` has been deprecated, and gallery examples use instead the
  ``data.astronaut()`` picture.
