scikit-image 0.22.0 (2023-11-03)#

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

Highlights#

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

  • Add inpainting example to gallery (#6853).

New Features#

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

API Changes#

  • Update minimal required NumPy version to 1.22 (#7005).

  • Update minimal required lazy_loader version to 0.3 (#7043).

  • 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).

Performance#

  • Add lazy loading to the skimage.feature submodule (#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).

Bug Fixes#

  • Add missing properties num_pixels and coords_scaled to skimage.measure.regionprops_table (#7039).

  • Fix too many values to unpack error with imageio 2.31.1 in video.rst (#7076).

  • Address error in skimage.filters.threshold_triangle when images with a uniform intensity are passed. In these cases the uniform intensity is returned as the threshold (#7098).

  • Fix error in skimage.color.lab2rgb for 1D input (#7116).

  • Make skimage.registration.phase_cross_correlation consistently return an array even if disambiguate=True (#7112).
