scikit-image 0.22.0rc1

We're happy to announce the release of scikit-image 0.22.0rc1!

New Features

• Add new image sequence skimage.data.palisades_of_vogt showing in-vivo tissue of the palisades of Vogt (#6858).

Performance

• Add lazy loading to the skimage.feature module (#6983).
• Add lazy loading to the skimage.graph submodule (#6985).
• Add lazy loading to the skimage.measure submodule (#6999).
• Add lazy loading to the skimage.transform submodule (#7009).
• Add lazy loading to the skimage.restoration submodule (#7021).
• Add lazy loading to the skimage.registration submodule (#7032).
• Avoid unnecessary padding in skimage.measure.block_resize (#7092).

Bug Fixes

• Add num_pixels and coords_scaled to regionprops_table (#7039).
• Update video.rst (#7076).
• For uniform intensity images, return intensity value as threshold (#7098).
• Fix color conversion error (#7116).
• Make phase_cross_correlation return ndarray when disambiguate=True (#7112).
• Allow extra_properties of non equal lengths to be passed correctly to regionprops_table (#7136).

API Changes

• Make PyWavelets an optional dependency which is only required for skimage.restoration.denoise_wavelet and skimage.restoration.estimate_sigma (#7156).
• Remove deprecated skimage.filters.inverse. Use skimage.filters.filter_inverse instead (#7161).
• Remove deprecated function skimage.filters.ridges.compute_hessian_eigenvalues. Use skimage.feature.hessian_matrix_eigvals on the results of skimage.feature.hessian_matrix instead (#7162).
• Remove deprecated automatic detection of the color channel in skimage.filters.gaussian. channel_axis=None now indicates a grayscale image. Set the color channel with channel_axis=-1 explicitly (#7164).
• Change number of returned arguments in skimage.registration.phase_cross_correlation. The function now always returns the 3 arguments shift, error, and phasediff (#7166).
• Deprecate return_error in skimage.registration.phase_cross_correlation (#7174).
