v0.25.1

scikit-image 0.25.1

We're happy to announce the release of scikit-image 0.25.1!

Bug Fixes

• Include centroid in __all__ of the PYI file in skimage.measure (#7652).
• Improve numerical stability of blur_effect (#7643).
• Because under-determined fits are unreliable, skimage.measure.EllipseModel will now warn and return False (no fit) when fewer than 5 data points are provided (#7648).
• Explicitly upcast data with dtype float16 to float32 in skimage.segmentation.random_walker; this fixes passing float16 on NumPy 1.26 (#7655).

Documentation

• Don't use removed QuadContourSet.collections in gallery example (#7638).
• Change old import convention in the gallery examples (#7630).

Infrastructure

• Make apigen.py work with editable hooks (#7647).
• Build Linux ARM wheels natively (#7664).

Maintenance

• Infer floating point type for sigma parameter (#7637).
• In skimage.segmentation.active_contour, change the type of the default argument for w_line to indicate it is a float (#7645).
• Temporarily disable parallel building of gallery (#7656).
• [pre-commit.ci] pre-commit autoupdate (#7649).
• Skip flaky test on azure (#7669).

v0.25.0

scikit-image 0.25.0

We're happy to announce the release of scikit-image 0.25.0!

New Features

• Add the new Gray-Level Co-occurrence Matrix (GLCM) properties "mean", "variance", "standard deviation" and "entropy" to skimage.feature.texture.graycoprops (#7375).
• Add the new skimage.morphology.footprint_rectangle supporting generation of rectangular or hyper-rectangular footprints in one function (#7566).

API Changes

• Complete the deprecation of and remove skimage.feature.plot_matches. Use skimage.feature.plot_matched_features going forward (#7487).
• Deprecate skimage.io.imshow, skimage.io.imshow_collection and skimage.io.show. Please use matplotlib, napari, etc. to visualize images (#7508).
• Remove deprecated skimage.morphology.skeletonize_3d; use skimage.morphology.skeletonize instead (#7572).
• Deprecate skimage.io plugin infrastructure (#7353).
• Switched to using the scipy.sparse array interface. For more details, see the note about the new scipy.sparse array interface here (#7576).
• Deprecate skimage.morphology.rectangle in favor of the new function skimage.morphology.footprint_rectangle (#7566).
• Deprecate skimage.morphology.square in favor of the new function skimage.morphology.footprint_rectangle (#7566).
• Deprecate skimage.morphology.cube in favor of the new function skimage.morphology.footprint_rectangle (#7566).

Enhancements

• Improve numerical stability of skimage.morphology.local_minima for extremely small floats (#7534).
• Make sure that skimage.feature.plot_matched_features uses the same random colors, if matches_color isn't provided explicitly (#7541).
• Allow passing a sequence of colors to the parameter matches_color in skimage.feature.plot_matched_features (#7541).

Performance

• skimage.feature.peak_local_max will now skip unnecessary distance computations in the case of min_distance=1. This results in performance improvements to functions like skimage.feature.blob_dog, skimage.feature.blob_log, skimage.feature.blob_doh and skimage.feature.corner_peaks that call peak_local_max internally (#7548).
• In skimage.featurepeak_local_max, skip unnecessary check for cases where min_distance > 1 is passed (#7548).

Bug Fixes

• Ensure that skimage.morphology.remove_objects_by_distance doesn't fail if the given integer dtype cannot be safely cast to the architecture specific size of intp, e.g. on i386 architectures (#7453).
• Fix degeneracy in skimage.draw.ellipsoid_stats when all semi-axes have the same length (#7473).
• Prevent skimage.morphology.thin from accidentally modifying the input image in case it is of dtype uint8 (#7469).
• Fix numerical precision error in skimage.measure.ransac. In some cases, ransac was stopping at the first iteration (#7065).
• Fix numerical precision error in skimage.measure.ransac; very small probabilities lead to -0 number of max trials (#7496).
• Ensure that RegionProperties objects returned by skimage.measure.regionprops can be deserialized with pickle (#7569).
• Fix edge case where setting watershed_lines=True in skimage.segmentation.watershed resulted in an incorrect solution (#7071).
• Fix the behavior of skimage.segmentation.watershed when the markers don't align with local minima by making sure every marker is evaluated before successive pixels (#7071).
• Fix dtype promotion in skimage.segmentation.join_segmentations if numpy.uint is used with NumPy<2 (#7292).

Documentation

• In skimage.morphology.skeletonize, clarify the expected image dtypes and how objects of different intensities are handled (#7456).
• Fix example section in docstring of skimage.feature.graycomatrix (#7297).
• Use conda-forge consistently in instructions for setting up the development environment (#7483).
• Use new CITATION.cff instead of CITATION.bib (#7505).
• Use correct spin test --coverage in contribution guide (#7515).
• Tweak advice to new developers; remove AI warning (#7522).
• Rework installation instructions (#7434).
• Improve the description of the image parameter in skimage.restoration.richardson_lucy (#7477).
• Account for empty arrays when counting segments per contour level in gallery example "Segment human cells (in mitosis)" (#7551).
• Fix typo in morphology doc (#7606).
• Change type description of parameter radius in skimage.morphology.ball from int to float (#7627).

Infrastructure

• Uncomment currentmodule directive again (#7492).
• Add CI to release nightly free-threaded wheels (#7481).
• Update deprecated configuration (#7501).
• Bump spin version to 0.11 (#7507).
• Ensure only a single type: label is present in PRs (#7512).
• Update pydata-sphinx-theme (#7511).
• Fix OpenBLAS s_cmp unresolved symbol error, update Emscripten CI testing (#7525).
• Render paragraphs in dormant message (#7549).
• Build sphinx documentation with parallel jobs (#7579).
• Don't check test coverage in CI (#7594).
• Explicitly setup conda on macos for wheel building (#7608).

Maintenance

• Verify all artifacts that have been attested by looping over them in CI (#7447).

• Add new class skimage.transform.ThinPlateSplineTransform, which can estimate and model non-linear transforms with thin-plate splines and allows image warping with skimage.transform.warp (#7040).
• Add skimage.morphology.remove_objects_by_distance, which removes labeled objects, ordered by size (default), until the remaining objects are a given distance apart (#4165).

Performance

• In skimage.feature.corner_fast, test four directions earlier, which should more than half the computation time for most cases (#7394).

Documentation

• Remove obsolete instruction about documenting changes (#7321).
• Clarify description of data_range parameter in skimage.metrics.structural_similarity (#7345).
• Update release process notes (#7402).

• Fix typos in skimage.measure.find_contours (#7411).
• Add algorithmic complexity description + suggested alternatives to skimage.restoration.rolling_ball docstring (#7424).
• Remove ineffective PR contribution clause (#7429).
• Clarify objection period for lazy consensus in SKIP 1 (#7020).
• Add a new gallery example "Use thin-plate splines for image warping" (#7040).
• Add a new gallery example on "Removing objects" based on their size or distance (#4165).

Infrastructure

• Escape user-controlled variables in GA workflow (#7415).
• Add generation of GitHub artifact attestations to built sdist and wheels before upload to PyPI (#7427).
• For publishing actions use the full length commit SHA (#7433).

• Add new class skimage.transform.ThinPlateSplineTransform, which can estimate and model non-linear transforms with thin-plate splines and allows image warping with skimage.transform.warp (#7040).
• Add skimage.morphology.remove_objects_by_distance, which removes labeled objects, ordered by size (default), until the remaining objects are a given distance apart (#4165).

Performance

• In skimage.feature.corner_fast, test four directions earlier, which should more than half the computation time for most cases (#7394).

Documentation

• Remove obsolete instruction about documenting changes (#7321).
• Clarify description of data_range parameter in skimage.metrics.structural_similarity (#7345).
• Update release process notes (#7402).
• Fix typo in docstring of skimage.measure.regionprops (#7405).
• Fix typos in skimage.measure.find_contours (#7411).
• Add algorithmic complexity description + suggested alternatives to skimage.restoration.rolling_ball docstring (#7424).
• Remove ineffective PR contribution clause (#7429).
• Clarify objection period for lazy consensus in SKIP 1 (#7020).
• Add a new gallery example "Use thin-plate splines for image warping" (#7040).
• Add a new gallery example on "Removing objects" based on their size or distance (#4165).

Infrastructure

• Escape user-controlled variables in GA workflow (#7415).
• Add generation of GitHub artifact attestations to built sdist and wheels before upload to PyPI (#7427).
• For publishing actions use the full length commit SHA (#7433).
• Be mindful of resources by canceling in-progress workflows (#7436).
• Add out-of-tree Pyodide builds in CI for scikit-image (#7350).

Maintenance

• Replace deprecated nose style setup/teardown with autouse fixtures (#7343).
• Temporarily pin macos-12 runner in CI (#7408).
• Fix NumPy2 dtype promotion issues in pywt dependent code (#7414).
• In skimage.util.compare_images, deprecate the parameter image2. Instead use image0, image1 to pass the compared images. Furthermore, all other parameters will be turned into keyword-only parameters once the deprecation is complete (#7322).
• Add support back for Python 3.9 to enhance compatibility with Numpy 2 (#7412).
• Disable ruff/pyupgrade rule UP038 (#7430).
