We might like to update the [dask-image contributing guide](https://image.dask.org/en/latest/contributing.html) to include: 1. Information about the GPU CI bot (see [here](https://docs.dask.org/en/stable/develop.html?highlight=gpu%20ci#gpu-ci), and/or 2. A link to the [main dask contributing guide](https://docs.dask.org/en/stable/develop.html)....

good first issue

cc: @jmdelahanty Hi dask-image developers! Normally an end-user may control which reader `pims.open()` uses to load images by simply increasing the `.class_priority` attribute of their preferred `pims` reader prior to...

A lot of people have put a lot of effort into `imread` lately. This is great, and it's really helped. However, we've still got a way to go. This is...

I wrote a wrapper around [skimage.pyramid_gaussian](https://scikit-image.org/docs/stable/auto_examples/transform/plot_pyramid.html) that uses [da.coarsen](https://docs.dask.org/en/stable/generated/dask.array.coarsen.html) and other dask and dask-image functions. You can find it [here](https://github.com/samwelborn/tomopyui/blob/main/tomopyui/backend/util/dask_downsample.py). This is a fix for people who want to pyramid...

I found myself reaching for an `imsave` function to compliment `imread`. Presumably this would have similar semantics, and would effectively map over the `skimage.io.imsave` function, or something else in pims....

Should we bump the minimum allowable dask version? I just got a dependabot alert in another repo indicating an update to dask=2021.10.0 is necessary: > An issue was discovered in...

This PR suggests a `dask-image` implementation for `ndimage.map_coordinates` which covers the case in which the provided coordinates fit into memory and the `input` array consists of a (potentially large) dask...

Hi, In preparing the NixOS packages for `dask-image` on aarch64-linux, we noticed that the following test has been failing since version 0.6.0 of dask-image: ``` _______ TestInvalidArguments.test_nan_blocksize[gaussian-nan-ValueError] _______ self =...

The `find_objects` implementation is not currently compatible with cupy. It'd be nice to try and change that in a future PR. See https://github.com/dask/dask-image/pull/240

The `find_objects` functionality is still quite new, and it would be good to get some performance testing done. Some previous discussion is here https://github.com/dask/dask-image/pull/240#discussion_r675591009 > > Second, I think it's...
