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.
