Announcement: scikit-image 0.16.1
๐ 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.๐ For more information, examples, and documentation, please visit our website:
๐ 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>__
.
๐ Accordingly, scikit-image 0.16 drops support for Python 3.5.
๐ 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>

๐ 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)
๐ Fixed by using the Ramp filter equation in the spatial domain as described
in the reference - ๐ 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)

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) - ๐ Fixed
skimage.morphology.medial_axis
. A wrong indentation in Cython
caused the function to not behave as intended. (#4060) - ๐ Fixed
skimage.restoration.denoise_bilateral
by correcting the padding in
the gaussian filter(#4080) - ๐ Fixed
skimage.measure.find_contours
when input image contains NaN.
Contours interesting NaN will be left open (#4150) - ๐ฒ Fixed
skimage.feature.blob_log
andskimage.feature.blob_dog
for 3D
images and anisotropic data (#4162) - Fixed
skimage.exposure.adjust_gamma
,skimage.exposure.adjust_log
,
andskimage.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)
