Hi Juan, The min of the image is -186.11397 and the max is 30790.521. That is why I got the error. Thanks for the reply and pointing out this page. I have more understandings on image data types for scikit-image.

Hi Vicky, What's the min and max of your "myimagearray"? As the error message says, float images should only contain values between -1 and 1. ie, myimagearray.max() should be less than 1, and myimagearray.min() should be greater than -1. Here's the relevant part of the documentation describing data types: http://scikit-image.org/docs/0.9.x/user_guide/data_types.html Hope that helps, Juan.

Step 1: Apply as a mentoring organization before 14 February (I can help with the documentation) Step 2: If that fails, register under the umbrella of the PSF Step 3: Solicit proposals from students (at that time, students should already have become involved in the community and have made pull requests under discussion) Step 4: Choose one, maximum two excellent contributions. Step 5: Spend about 5 hours a week for two months mentoring students. The projects need to be large enough in scope to cover 2 months (a good example would be Ankit's feature detectors) and make a significant and needed contribution to the project. An example of such a project for this year would be to implement a registration submodule. The reason I am hesitant to take on more than one candidate is that we are still busy reviewing and refactoring Chintak and Marc's contributions from last year (inpainting and graph cuts).

Hi all, How about implementing Wavelet based techniques? Like Image Processing using Wavelet Transform. Decompose the image into wavelet domain Alter the wavelet coefficients as per the application such as denoising, compression, edge enhancement, etc. Reconstruct the image with the altered wavelet coefficients. I am looking forward to contribute.Will this help scikit-image? Suggestions needed.

I would feel a bit guilty having my name on the paper without contributing any text to it; I'm not sure yet if that guilt is strong enough to make me contribute to the writing (again, because I hate writing papers---I still love scikit-image). In short, I would be fine if I were left off the authors list (assuming I haven't guilted myself into writing a section of the paper)---it would great to be listed, but I also think an author on a paper should contribute to the writing (... which, sadly, isn't always the case in academia... actually you don't even have to contribute that much to the research either... sorry I may still have some post-academia hang ups:P).

I'm not positive about this new criterion. My gut feeling is that it should be a bit nuanced on either side. For example, even if Tony doesn't write a single line for the paper, I still think he should be an author. Conversely, I don't think someone who has not thus far contributed a single line of code, issue, or tutorial should be able to jump in, write a few paragraphs, and be an author on the paper. Having said that, I do agree that "core contributors" is too nebulous, so, for example, I'd be perfectly comfortable having François on the author list. Juan.

Is this too long? By the way, you can make really nice panoramas if you export the transformed images to TIFF and stitch them together using "enblend". Since blending is not really in our scope, it's probably fine to use that as the final component, if you want a particularly shiny result. Stéfan

Hi all, Working on the scikit-image paper, I've had some further thoughts about authorship (yes, this is much harder than writing the paper :). I suggest the following (what I consider to be) fair guideline: 1) Anyone who contributes significantly to the writing of the paper gets their name in the authors list 2) All other contributors are included in the "scikit-image contributors" author To me, this feels like the fairest way to reward those who time into writing the paper, while also giving credit to all of those whose work is described therein. I felt uncomfortable adding all "core contributors" to the authors list, since that concept is becoming more and more nebulous with GitHub PRs. I'd like to hear your thoughts. Stéfan

"Cythonize" not working on OSX?
by Juan Nunez-Iglesias 03 Feb '14

03 Feb '14

Hi all, As others have noted (see e.g. here<https://github.com/scikit-image/scikit-image/pull/873#issuecomment-33875298>), the change from using a cython command to the "cythonize" function call within skimage/_build.py has broken the build process on some machines. Cython files don't get compiled to .c files automatically and the build fails with errors such as: clang: error: no such file or directory: 'orb_cy.c' clang: error: no input files clang: error: no such file or directory: 'orb_cy.c' clang: error: no input files Calling Cython manually for all the files works, but obviously this is not a solution. Does anyone know what's going on here? Juan.

Help with using filter.rank.median
by Aman Thakral 01 Feb '14

01 Feb '14

Hi all, I'm currently trying to use a median filter on my data, an am getting an error that I can't seem to debug. I'm taking the difference of two images (both numpy.float64), scaling them between -1 and 1, and trying to apply a median filter. My image satisfies the conditions for being between -1 and 1 when I do the following test: print diff.min()/dmax < -1.0 -> returns False (LHS evals to -1.0) print diff.max()/dmax > 1.0 -> returns False (LHS evals to 0.663919388648) The statement causing the error: filtered = fltr.median(diff/dmax, selem) where diff is my difference, and dmax is my scaling adjustment, selem is a disk of radius 2 This gives me the following traceback. Traceback (most recent call last): File "/home/clustering.py", line 138, in image_ratio filtered = fltr.median(diff/dmax/2.+0.5, selem, mask=m.astype(np.bool)) File "/usr/local/lib/python2.7/dist-packages/skimage/filter/rank/generic.py", line 369, in median out=out, mask=mask, shift_x=shift_x, shift_y=shift_y) File "/usr/local/lib/python2.7/dist-packages/skimage/filter/rank/generic.py", line 71, in _apply out_dtype) File "/usr/local/lib/python2.7/dist-packages/skimage/filter/rank/generic.py", line 34, in _handle_input image = img_as_ubyte(image) File "/usr/local/lib/python2.7/dist-packages/skimage/util/dtype.py", line 358, in img_as_ubyte return convert(image, np.uint8, force_copy) File "/usr/local/lib/python2.7/dist-packages/skimage/util/dtype.py", line 191, in convert raise ValueError("Images of type float must be between -1 and 1.")
