    Announcement: scikit-image 0.16.1

    ๐Ÿš€ We're happy to announce the release of scikit-image v0.16.1!

    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.

    ๐Ÿ“š For more information, examples, and documentation, please visit our website:

    https://scikit-image.org

    ๐Ÿš€ Starting from this release, scikit-image will follow the recently
    introduced NumPy deprecation policy, NEP 29 <https://github.com/numpy/numpy/blob/master/doc/neps/nep-0029-deprecation_policy.rst>__.
    ๐Ÿ‘ Accordingly, scikit-image 0.16 drops support for Python 3.5.
    ๐Ÿš€ This release of scikit-image officially supports Python 3.6 and 3.7.

    Special thanks to Matthias Bussonnier for Frappuccino <https://github.com/Carreau/frappuccino>__, which helped us catch all API
    ๐Ÿ”„ changes and nail down the APIs for new features.

    ๐Ÿ†• New Features

      nrme, psd) and segmentation metrics (adapted rand error, variation of

      occurring value within its neighborhood -- skimage.filters.majority
      (#3836, #3839)
    • Multi-level threshold "multi-Otsu" method, a thresholding algorithm
      ๐Ÿ‘‰ used to separate the pixels of an input image into several classes by

    ๐Ÿ›  Bugfixes

    • Corrected error with scales attribute in ORB.detect_and_extract (#2835)
      The scales attribute wasn't taking into account the mask, and thus was using
      an incorrect array size.
    • Correct for bias in Inverse Randon Transform (skimage.transform.irandon) (#3067)
      ๐Ÿ›  Fixed by using the Ramp filter equation in the spatial domain as described
      in the reference
    • ๐Ÿ›  Fix a rounding issue that caused a rotated image to have a
      different size than the input (skimage.transform.rotate) (#3173)
    • RANSAC uses random subsets of the original data and not bootstraps. (#3901,
      #3915)
    • Canny now produces the same output regardless of dtype (#3919)
    • Geometry Transforms: avoid division by zero & some degenerate cases (#3926)
    • Fixed float32 support in denoise_bilateral and denoise_tv_bregman (#3936)
    • ๐Ÿ›  Fixed computation of Meijering filter and avoid ZeroDivisionError (#3957)
    • ๐Ÿ›  Fixed skimage.filters.threshold_li to prevent being stuck on stationnary
      points, and thus at local minima or maxima (#3966)
    • Edited skimage.exposure.rescale_intensity to return input image instead of
      nans when all 0 (#4015)
    • ๐Ÿ›  Fixed skimage.morphology.medial_axis. A wrong indentation in Cython
      caused the function to not behave as intended. (#4060)
    • ๐Ÿ›  Fixed skimage.restoration.denoise_bilateral by correcting the padding in
      the gaussian filter(#4080)
    • ๐Ÿ›  Fixed skimage.measure.find_contours when input image contains NaN.
      Contours interesting NaN will be left open (#4150)
    • ๐ŸŒฒ Fixed skimage.feature.blob_log and skimage.feature.blob_dog for 3D
      images and anisotropic data (#4162)
    • Fixed skimage.exposure.adjust_gamma, skimage.exposure.adjust_log,
      and skimage.exposure.adjust_sigmoid such that when provided with a 1 by
      1 ndarray, it returns 1 by 1 ndarrays and not single number floats (#4169)

    ๐Ÿ—„ Deprecations

    Parameter neighbors in skimage.measure.convex_hull_object has been
    ๐Ÿšš deprecated in favor of connectivity and will be removed in version 0.18.0.

    ๐Ÿ—„ The following functions are deprecated in favor of the skimage.metrics
    module (#4025):

    • skimage.measure.compare_mse
    • skimage.measure.compare_nrmse
    • skimage.measure.compare_psnr

    - skimage.measure.compare_ssim

    The function skimage.color.guess_spatial_dimensions is deprecated and
    ๐Ÿšš will be removed in 0.18 (#4031)

    The argument bc in skimage.segmentation.active_contour is
    ๐Ÿ—„ deprecated.

    ๐Ÿšš The function skimage.data.load is deprecated and will be removed in 0.18
    (#4061)

    ๐Ÿ—„ The function skimage.transform.match_histogram is deprecated in favor of
    skimage.exposure.match_histogram (#4107)

    The parameter neighbors of skimage.morphology.convex_hull_object is
    ๐Ÿ—„ deprecated.

    The skimage.transform.randon_tranform function will convert input image
    0๏ธโƒฃ of integer type to float by default in 0.18. To preserve current behaviour,
    set the new argument preserve_range to True. (#4131)
