Participating in GSoC 2016? Project Ideas ?

Hi, I wanted to know if scikit-image will be participating in GSoC 2016? If yes, then we(less experienced contributors) would greatly benefit if a list of project ideas is released, so that we can do our homework before application period begins. Thanks, Utkarsh

Ok thanks, exposure.rescale_intensity(data, in_range=(-1, 1)) seems to do the trick. Was -10,10 a typo? Is there any concern for loss of information when doing a rescale?

Hi! Thanks for the reply The reason I wanted to use img_as_float is because I eventually plan to use many functions and I thought I should get the image into a format that scikit-image likes before proceeding. However, as you suggested, the function I want to use immediately is transform.rotate() which does have a preserve scale option, and that did fix my problem. Should I just use this on every function?

ValueError: Images of type float must be between -1 and 1.

Hi, I am having a problem trying to create an image object from an array. The problem is the array extends beyond -1 and 1. The pixel values are raw 32bit float values from a detector. array.dtype float32 summary(array) Mean: 0.00656827 Min: -6.1125 Median: 1.09516e-08 Max: 3.69815 image = skimage.img_as_float(array) File "/home/user/anaconda2/lib/python2.7/site-packages/skimage/util/dtype.py", line 291, in img_as_float return convert(image, np.float64, force_copy) File "/home/user/anaconda2/lib/python2.7/site-packages/skimage/util/dtype.py", line 195, in convert raise ValueError("Images of type float must be between -1 and 1.") ValueError: Images of type float must be between -1 and 1 I am using version 0.11.3 via anaconda on fedora 23 Sometimes I can get img_as_float to work if I use astype on the array first, but then it doesn't seem to change the values, and then skimage.io.Image() will fail with a similar error Thanks in advance for any help.

Hey Stéfan, The last date for applying under PSF umbrella is March 7, exactly one month from now. I guess we have good time to take a decision regarding GSoC participation. -- Himanshu Mishra

Hi, I am interested to be a part of this community. I went through the last year's proposed projects at GSoC and DTW was one of them. Was it taken up? Otherwise, I would like to take it up as my GSoC project for this year. Regards.

One more request, especially to the core team: could we restrain ourselves from adding new PRs to the 0.12 milestone, except for bad bug fixes? We need to converge at some point :-).
