ANN : FreDo-Editor 0.01dev, a frequency domain image editor
by Vighnesh Birodkar 21 Aug '15

21 Aug '15

Hello This is to announce Fredo-Editor, a frequency domain image editor. Website: http://fredo-editor.github.io/ Source: https://github.com/fredo-editor/FreDo Installation: http://fredo-editor.github.io/install/ Tutorial: http://fredo-editor.github.io/tutorial/ Fredo-Editor (Frequency Domain Editor) is a GUI for editing images in their frequency spectrum. It is intended for academic/research purposes. It's main goal is to help the user understand the Fourier Transform, by seeing it taking effect in real time. It can also be used to remove periodic noise from images as seen here: http://fredo-editor.github.io/gallery/ At this point, only basic square shape modifications are possible. I want to gather feedback to know what features to add. I intend this to be a small. handy tool for researchers, students and teachers to explore, visualize and understand the Fourier Transform and frequency domain filtering. Any comments and criticisms are welcome. *Note:* Fredo-Editor is still under development and its features and functionality is subject to change. Attachments input.png - The input image and its Fourier transform output.png - Corrected image and its Fourier Transform Thanks Vighnesh

Large image pyramids using dask
by Don Venable 17 Aug '15

17 Aug '15

I've been using scikit-image and dask to play with very large image rasters, and I have a gist for creating an image-pyramid using dask. As the chunk-shapes change during downsampling, you I couldn't use the apply_parallel() function from the existing PR on using dask + scikit-image. Was talking with @blink1073 and he mentioned that it might be useful/interesting to the community, so wanted to see what you thought. Here's a link: https://gist.github.com/venabled/669caeb2615e9ed1d952

Re: skimage is marked for autoremoval from testing

Lena is the problem. We're going to have to remove that from the package. OpenCV had the exact same issue, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794856 Three potential solutions come to mind: - Remove `lena` from the package, raising an error informing the user the image is not free and directing them to `astronaut`. - Simply alias all queries for `lena` to `astronaut`, with a warning. - Instead of loading from disk, have `imread` obtain this image from a permalinked URL. Ideally an aliased one we can redirect if a host dies. We could have a couple fallback URLs, too. Biggest question is what to do if no internet connection is available. I favor the first or third solutions. Josh On Friday, August 14, 2015 at 11:52:30 PM UTC-5, stefanv wrote: > > Can I convince anyone to look at the following?

Our test suite currently relies on comparing the morphology results (derived from Lena) of MATLAB to those of scikit-image. We have two options: a) Set up small, hand calculated tests to replace the existing ones. b) Reproduce the existing ones with a different image, such as astronaut. Does anyone have the inclination for (a) or acess to MATLAB for (b)? Stéfan

Removal of non-free files from repository
by Stefan van der Walt 07 Aug '15

07 Aug '15

Hi, all Please refer to this Debian bug: https://bugs.debian.org/771191 It has been noted that the Lena image we distribute (even though we no longer use it ourselves anywhere) is not fully free. In other words, Debian would be forced to release a version of scikit-image without it. I thought we could make their lives easier by simply removing the image from the main repository. What do you think? One question is whether we also remove ``data.lena``, or change it to return astronaut. Stéfan
