In the struggle of survival, it is the art of hunting and weapons that made it possible for humans to reach so far in the race. So, technically we are evolutionarily conditioned to hunt, and modern warfare is all about advanced guns. Unfortunately, we don’t have the liberty of real-life game hunting, so the next best possible options are to buy the https://bestpaintballguns.us/best-paintball-guns best paintball guns and satisfy your inherent urge to hunt and keep your killer instinct alive.

Announcing the 2020 John Hunter Excellence in Plotting Contest
by Nelle Varoquaux 13 May '20

13 May '20

Dear all, I apologize for the cross posting. This is a reminder for the John Hunter Excellence in Plotting Contest. In memory of John Hunter, we are pleased to announce the John Hunter Excellence in Plotting Contest for 2020. This open competition aims to highlight the importance of data visualization to scientific progress and showcase the capabilities of open source software. Participants are invited to submit scientific plots to be judged by a panel. The winning entries will be announced and displayed at SciPy 2020 or announced in the John Hunter Excellence in Plotting Contest website and youtube channel. John Hunter’s family are graciously sponsoring cash prizes for the winners in the following amounts: - 1st prize: $1000 - 2nd prize: $750 - 3rd prize: $500 - Entries must be submitted by June 1st to the form at https://forms.gle/SrexmkDwiAmDc7ej7 - Winners will be announced at Scipy 2020 in Austin, TX or publicly on the John Hunter Excellence in Plotting Contest website and youtube channel - Participants do not need to attend the Scipy conference. - Entries may take the definition of “visualization” rather broadly. Entries may be, for example, a traditional printed plot, an interactive visualization for the web, a dashboard, or an animation. - Source code for the plot must be provided, in the form of Python code and/or a Jupyter notebook, along with a rendering of the plot in a widely used format. The rendering may be, for example, PDF for print, standalone HTML and Javascript for an interactive plot, or MPEG-4 for a video. If the original data can not be shared for reasons of size or licensing, "fake" data may be substituted, along with an image of the plot using real data. - Each entry must include a 300-500 word abstract describing the plot and its importance for a general scientific audience. - Entries will be judged on their clarity, innovation and aesthetics, but most importantly for their effectiveness in communicating a real-world problem. Entrants are encouraged to submit plots that were used during the course of research or work, rather than merely being hypothetical. - SciPy and the John Hunter Excellence in Plotting Contest organizers reserves the right to display any and all entries, whether prize-winning or not, at the conference, use in any materials or on its website, with attribution to the original author(s). - Past entries can be found at https://jhepc.github.io/ - Questions regarding the contest can be sent to jhepc.organizers(a)gmail.com John Hunter Excellence in Plotting Contest Co-Chairs Madicken Munk Nelle Varoquaux

scikit-image 0.17.1 release
by Emmanuelle Gouillart 09 May '20

09 May '20

Announcement: scikit-image 0.17.1 ================================= We're happy to announce the release of scikit-image v0.17.1! 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 Many thanks to the 54 authors who contributed the amazing number of 213 merged pull requests! scikit-image is a community-based project and we are happy that this number includes first-time contributors to scikit-image. Special thanks for the release to the Cython team, who helped us make our code compatible with their coming Cython 3.0 release. The full release notes are available on https://scikit-image.org/docs/stable/release_notes_and_installation.html?hi… Please report any bug reports or suggestions on https://github.com/scikit-image/scikit-image/issues/new. Community support is available on https://forum.image.sc/tag/scikit-image. New Features ------------ - Hyperparameter calibration of denoising algorithms with `restoration.calibrate_denoiser` (#3824), with corresponding gallery example and tutorial. - `measure.profile_line` has a new `reduce_func` parameter to accept a reduction operation to be computed on pixel values along the profile (#4206) - nD windows for reducing spectral leakage when computing the FFT of n-dimensional images, with `filters.window` (#4252) (with new gallery example) - Add Minkowski distance metric support to corner_peak (#4218) - `util.map_array` was introduced to map a set of pixel values to another one (for example to map region labels to the size of regions in an image of labels) #4612 and #4646 - Masked marching cubes (#3829) - The SLIC superpixel algorithm now accepts a mask to exclude some parts of the image and force the superpixel boundaries to follow the boundary of the mask (#3850) - Pooch -- on the fly download of datasets from github: we introduced the possibility to include larger datasets in the `data` submodule, thanks to the `pooch` library. `data.download_all` fetches all datasets. (#3945) - Starting with this version, our gallery examples now have links to run the example notebook on a binder instance. (#4543) New doc tutorials and gallery examples have been added to the use of regionprops_table (#4348) geometrical transformations (#4385), and the registration of rotation and scaling with no shared center (#4515). A new section on registration has been added to the gallery (#4575). Improvements ------------ - scikit-image aims at being fully compatible with 3D arrays, and when possible with nD arrays. nD support has been added to color conversion functions (#4418), to the CLAHE `exposure.equalize_adapthist` algorithm (#4598) and to the Sobel, Scharr, and Prewitt filters (#4347). - Multichannel support for denoise_tv_bregman (#4446) - The memory footprint of `segmentation.relabel_sequential` has been reduced in the case of labels much larger than the number of labels (#4612) - Random ellipses are now possible in `draw.random_shapes` (#4493) - Add border conditions to ridge filters (#4396) - `segmentation.random_walker` new Jacobi preconditioned conjugate gradient mode (#4359) and minor corrections #4630 - Warn when rescaling with NaN in exposure.intensity_range (#4265) We have also improved the consistency of several functions regarding the way they handle data types - Make dtype consistent in filters.rank functions (#4289) - Fix colorconv float32 to double cast (#4296) - Prevent radon from upcasting float32 arrays to double (#4297) - Manage iradon_sart input and output data type (#4300) API Changes ----------- - When used with floating point inputs, ``denoise_wavelet`` no longer rescales the range of the data or clips the output to the range [0, 1] or [-1, 1]. For non-float inputs, rescaling and clipping still occurs as in prior releases (although with a bugfix related to the scaling of ``sigma``). - For 2D input, edge filters (Sobel, Scharr, Prewitt, Roberts, and Farid) no longer set the boundary pixels to 0 when a mask is not supplied. This was changed because the boundary mode for `scipy.ndimage.convolve` is now ``'reflect'``, which allows meaningful values at the borders for these filters. To retain the old behavior, pass ``mask=np.ones(image.shape, dtype=bool)`` (#4347) - When ``out_range`` is a range of numbers and not a dtype in :func:`skimage.exposure.rescale_intensity`, the output data type will always be float (#4585) - The values returned by :func:`skimage.exposure.equalize_adapthist` will be slightly different from previous versions due to different rounding behavior (#4585) - Move masked_register_translation from feature to registration (#4503) - Move register_translation from skimage.feature to skimage.registration (#4502) - Move watershed from morphology to segmentation (#4443) - Rename draw.circle() to draw.disk() (#4428) - The forward and backward maps returned by :func:`skimage.segmentation.relabel_sequential` are no longer NumPy arrays, but more memory-efficient `ArrayMap` objects that behave the same way for mapping. See the ``relabel_sequential`` documentation for more details. To get NumPy arrays back, cast it as a NumPy array: ``np.asarray(forward_map)`` (#4612) Bugfixes -------- - ``denoise_wavelet``: For user-supplied `sigma`, if the input image gets rescaled via ``img_as_float``, the same scaling will be applied to `sigma` to preserve the relative scale of the noise estimate. To restore the old, behaviour, the user can manually specify ``rescale_sigma=False``. - Fix Frangi artefacts around the image (#4343) - Fix Negative eigenvalue in inertia_tensor_eigvals due to floating point precision (#4589) - Fix morphology.flood for F-ordered images (#4556) - Fix h_maxima/minima strange behaviors on floating point image input (#4496) - Fix peak_local_max coordinates ordering (#4501) - Sort naturally peaks coordinates of same amplitude in peak_local_max (#4582) - Fix denoise_nl_means data type management (#4322) - Update rescale_intensity to prevent under/overflow and produce proper output dtype (#4585) (other small bug fixes are part of the list of other pull requests at the end) Deprecations ------------ The minimal supported Python version by this release is 3.6. - Parameter ``inplace`` in skimage.morphology.flood_fill has been deprecated in favor of ``in_place`` and will be removed in version scikit-image 0.19.0 (#4250). - ``skimage.segmentation.circle_level_set`` has been deprecated and will be removed in 0.19. Use ``skimage.segmentation.disk_level_set`` instead. - ``skimage.draw.circle`` has been deprecated and will be removed in 0.19. Use ``skimage.draw.disk`` instead. - Deprecate filter argument in iradon due to clash with python keyword (#4158) - Deprecate marching_cubes_classic (#4287) - Change label2rgb default background value from -1 to 0 (#4614) - Deprecate rgb2grey and grey2rgb (#4420) - Complete deprecation of circle in morphsnakes (#4467) - Deprecate non RGB image conversion in rgb2gray (#4838, #4439), and deprecate non gray scale image conversion in gray2rgb (#4440) 54 authors added to this release [alphabetical by first name or login] ---------------------------------------------------------------------- - aadideshpande (aadideshpande) - Alexandre de Siqueira - Asaf Kali - Cedric - D-Bhatta (D-Bhatta) - Danielle - Davis Bennett - Dhiren Serai - Dylan Cutler - Egor Panfilov - Emmanuelle Gouillart - Eoghan O'Connell - Eric Jelli - Eric Perlman - erjel (erjel) - Evan Widloski - François Boulogne - Gregory R.
