Bumps scikit-image from 0.17.2 to 0.21.0.

Release notes

Sourced from scikit-image's releases.

v0.21.0

We're happy to announce the release of scikit-image 0.21.0! 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.

For more information, examples, and documentation, please visit our website: https://scikit-image.org

Highlights

• Last release to support Python 3.8
• Unified API for PRNGs

New Features

• Implement Fisher vectors in scikit-image (#5349).
• Add support for y-dimensional shear to the AffineTransform (#6752).

API Changes

In this release, we unify the way seeds are specified for algorithms that make use of pseudo-random numbers. Before, various keyword arguments (sample_seed, seed, random_seed, and random_state) served the same purpose in different places. These have all been replaced with a single rng argument, that handles both integer seeds and NumPy Generators. Please see the related SciPy discussion, as well as Scientific Python SPEC 7 that attempts to summarize the argument.

• Unify API on seed keyword for random seeds / generator (#6258).
• Refactor _invariant_denoise to denoise_invariant (#6660).
• Expose color.get_xyz_coords in public API (#6696).
• Make join_segmentations return array maps from output to input labels (#6786).
• Unify pseudo-random seeding interface (#6922).
• Change geometric transform inverse to property (#6926).

Enhancements

• Bounding box crop (#5499).
• Add support for y-dimensional shear to the AffineTransform (#6752).
• Make join_segmentations return array maps from output to input labels (#6786).
• Check if spacing parameter is tuple in regionprops (#6907).
• Enable use of rescale_intensity with dask array (#6910).

Performance

• Add lazy loading to skimage.color submodule (#6967).
• Add Lazy loading to skimage.draw submodule (#6971).
• Add Lazy loader to skimage.exposure (#6978).
• Add lazy loading to skimage.future module (#6981).

Bug Fixes

• Fix and refactor deprecated decorator to deprecate_func (#6594).
• Refactor _invariant_denoise to denoise_invariant (#6660).
• Expose color.get_xyz_coords in public API (#6696).
• shift and normalize data before fitting circle or ellipse (#6703).
• Showcase pydata-sphinx-theme (#6714).
• Fix matrix calculation for shear angle in AffineTransform (#6717).
• Fix threshold_li(): prevent log(0) on single-value background. (#6745).
