scikit-image 0.14.0 release notes#

We’re happy to announce the release of scikit-image v0.14.0!

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.

This is the last major release with official support for Python 2.7. Future releases will be developed using Python 3-only syntax.

However, 0.14 is a long-term support (LTS) release and will receive bug fixes and backported features deemed important (by community demand) until January 1st 2020 (end of maintenance for Python 2.7; see PEP 373 for details).

For more information, examples, and documentation, please visit our website:

http://scikit-image.org

New Features#

  • Lookfor function to search across the library: skimage.lookfor. (#2713)

  • nD support for skimage.transform.rescale, skimage.transform.resize, and skimage.transform.pyramid_* transforms. (#1522)

  • Chan-Vese segmentation algorithm. (#1957)

  • Manual segmentation with matplotlib for fast data annotation: skimage.future.manual_polygon_segmentation, skimage.future.manual_lasso_segmentation. (#2584)

  • Hysteresis thresholding: skimage.filters.apply_hysteresis_threshold. (#2665)

  • Segmentation with morphological snakes: skimage.segmentation.morphological_chan_vese (2D), skimage.segmentation.morphological_geodesic_active_contour (2D and 3D). (#2791)

  • nD support for image moments: skimage.measure.moments_central, skimage.measure.moments_central, skimage.measure.moments_normalized, skimage.measure.moments_hu. This change leads to 3D/nD compatibility for many regionprops. (#2603)

  • Image moments from coordinate input: skimage.measure.moments_coords, skimage.measure.moments_coords_central. (#2859)

  • Added 3D support to blob_dog and blob_log. (#2854)

  • Inertia tensor and its eigenvalues can now be computed outside of regionprops; available in skimage.measure.inertia_tensor. (#2603)

  • Cycle-spinning function for approximating shift-invariance by averaging results from a series of spatial shifts: skimage.restoration.cycle_spin. (#2647)

  • Haar-like feature: skimage.feature.haar_like_feature, skimage.feature.haar_like_feature_coord, skimage.feature.draw_haar_like_feature. (#2848)

  • Data generation with random_shapes function: skimage.draw.random_shapes. (#2773)

  • Subset of LFW (Labeled Faces in the Wild) database: skimage.data.cbcl_face_database. (#2905)

  • Fully reworked montage function (now with a better padding behavior): skimage.util.montage. (#2626)

  • YDbDr colorspace conversion routines: skimage.color.rgb2ydbdr, skimage.color.ydbdr2rgb. (#3018)

Improvements#

  • VisuShrink method for skimage.restoration.denoise_wavelet. (#2470)

  • New max_ratio parameter for skimage.feature.match_descriptors. (#2472)

  • skimage.transform.resize and skimage.transform.rescale have a new anti_aliasing option to avoid aliasing artifacts when down-sampling images. (#2802)

  • Support for multichannel images for skimage.feature.hog. (#2870)

  • Non-local means denoising (skimage.restoration.denoise_nl_means) has a new optional parameter, sigma, that can be used to specify the noise standard deviation. This enables noise-robust patch distance estimation. (#2890)

  • Mixed dtypes support for skimage.measure.compare_ssim, skimage.measure.compare_psnr, etc. (#2893)

  • New alignment parameter in skimage.feature.plot_matches. (#2955)

  • New seed parameter in skimage.transform.probabilistic_hough_line. (#2960)

  • Various performance improvements. (#2821, #2878, #2967, #3035, #3056, #3100)

Bugfixes#

  • Fixed skimage.measure.regionprops.bbox_area returning incorrect value. (#2837)

  • Changed gradient and L2-Hys norm computation in skimage.feature.hog to closely follow the paper. (#2864)

  • Fixed skimage.color.convert_colorspace not working for YCbCr, YPbPr. (#2780)

  • Fixed incorrect composition of projective transformation with inverse transformation. (#2826)

  • Fixed bug in random walker appearing when seed pixels are isolated inside pruned zones. (#2946)

  • Fixed rescale not working properly with different rescale factors in multichannel case. (#2959)

  • Fixed float and integer dtype support in skimage.util.invert. (#3030)

  • Fixed skimage.measure.find_contours raising StopIteration on Python 3.7. (#3038)

  • Fixed platform-specific issues appearing in Windows and/or 32-bit environments. (#2867, #3033)

API Changes#

  • skimage.util.montage. namespace has been removed, and skimage.util.montage.montage2d function is now available as skimage.util.montage2d.

  • skimage.morphology.binary_erosion now uses True as border value, and is now consistent with skimage.morphology.erosion.

Deprecations#

  • freeimage plugin has been removed from skimage.io.

  • skimage.util.montage2d is deprecated and will be removed in 0.15. Use skimage.util.montage function instead.

  • skimage.novice is deprecated and will be removed in 0.16.

  • skimage.transform.resize and skimage.transform.rescale have a new anti_aliasing option that avoids aliasing artifacts when down-sampling images. This option will be enabled by default in 0.15.

  • regionprops will use row-column coordinates in 0.16. You can start using them now with regionprops(..., coordinates='rc'). You can silence warning messages, and retain the old behavior, with regionprops(..., coordinates='xy'). However, that option will go away in 0.16 and result in an error. This change has a number of consequences. Specifically, the “orientation” region property will measure the anticlockwise angle from a vertical line, i.e. from the vector (1, 0) in row-column coordinates.

  • skimage.morphology.remove_small_holes min_size argument is deprecated and will be removed in 0.16. Use area_threshold instead.
