Hi, Here are some implementations of Non-Local Means Denoising you might be interested in for reference/comparison: Image Processing On Line Journal (Antoni Buades, Bartomeu Coll, and Jean-Michel Morel): http://www.ipol.im/pub/art/2011/bcm_nlm/ Pierrick CoupÃ©'s website: https://sites.google.com/site/pierrickcoupe/softwares/denoising-for-medical… ITK implementation in the Baby Brain Toolkit, from FranÃ§ois Rousseau: https://github.com/rousseau/fbrain/blob/master/Code/Denoising/btkNLMTool.txx The first one provides an online demo, is easy to wrap in cython, but is only 2D whereas the two others handle 3D images.

Juan, You also might want to look into using a testing framework such as nose (https://nose.readthedocs.org/en/latest/) for running your unit tests. A number of scientific python packages use this package including scikit-image. If you name the file and functions/classes containing your unit tests correctly, nose will automatically collect and run your tests. In addition, you can use the handy nosetests command which will set the exit value correctly. If you look at the .travis.yml file for scikits-image you will see that on line 66 nosetests is used to run runs the unit tests. This same method is used in many other scientific python packages Cheers, - Jonathan On 01/21/2014 12:06 AM, Ralf Gommers wrote: > > > > On Tue, Jan 21, 2014 at 2:00 AM, Juan Nunez-Iglesias > <jni.soma(a)gmail.com <mailto:jni.soma@gmail.com>> wrote: > > Hi guys, > > A bit off-topic but I hope someone will be able to help trivially... > > I'm trying to run Travis on my own gala repository (you might > remember gala from my scipy2012 talk, when it was called ray).

Hi, Does anyone have access to a PowerPC machine? It would be helpful to have a backtrace on the following error in FreeImage: https://buildd.debian.org/status/fetch.php?pkg=skimage&arch=powerpc&ver=0.9… Thanks Stéfan

Help with Travis

Hi guys, A bit off-topic but I hope someone will be able to help trivially... I'm trying to run Travis on my own gala repository (you might remember gala from my scipy2012 talk, when it was called ray). It appeared to be working fine, but actually it's giving me a little green dot when in fact a bunch of tests are failing! https://travis-ci.org/jni/gala/builds/16860892 Here's the corresponding .travis.yml file: https://github.com/jni/gala/blob/tree-agglo/.travis.yml What am I doing wrong? How can I make it so the test failures result in build failures? Thanks, Juan.

Review of PR : FAST and ORB
by Ankit Agrawal 19 Jan '14

19 Jan '14

Hi all, The FAST and ORB pull request<https://github.com/scikit-image/scikit-image/pull/834>needs a final round of review. Johannes is done with some crucial design changes on the original PR<https://github.com/scikit-image/scikit-image/pull/699>. Please review it if you have some time. This might sound pretty lame, but merging this PR will motivate me to complete the work on FREAK descriptor<https://github.com/scikit-image/scikit-image/pull/729>. Thank you. Regards, Ankit.

Good to hear. Let me know how to improve the Development section and I could certainly contribute another example - not sure how many examples we want to include?
