io.imsave() problems with passing arguments to plugin "freeimage"
by Sigmund July 12, 2012

July 12, 2012

Hallo! To read uncompressed TIFF files I use the freeimage plugin. The reading works great but since last week I need to save a summed Image. I used the io.imsave() with the freeimage plugin but by default it writs a compressed TIFF file. The freeimage documentation provides Flags to use for different compressions or for a non compressed type (TIFF_NONE). Can someone tell me how to pass theses Flags to the plugin? I saw that Christophs 'tifffile' plugin does the job but still I would like to know how to use the freeimage plug-n for it. Thanks! Siggi

Re: Help to debug FreeImage on SPARC

Oh, ugh, wow. That's unexpected. What's the context / where is the segfault? Perhaps I can help by looking at the offending code.

Help to debug FreeImage on SPARC
by Stéfan van der Walt June 18, 2012

June 18, 2012

Hi, all The 0.6 release is lagging behind, since I'm struggling to debug a segfault that occurs when loading uint16 images via FreeImage on a SPARC. Is there anyone with experience on this platform, or who would like to help debug the issue? Thanks in advance, Stéfan

Segmentation algorithms
by Andreas Mueller June 18, 2012

June 18, 2012

Hi everybody. I was wondering whether you are interested in having more image segmentation algorithms in skimage. As far as I can see, there is mainly watershed there at the moment. I'd like to implement mean shift, quick shift, Felsenzwalb's graph based method and a k-means based method. Some of these are particularly interesting for super pixel creation. Also: is there a strong desire do support both 2d and 3d images? (or even n-d?) I haven't been following the project to closely recently. Cheers, Andy

Hi Jaidev. To answer both of your questions: I was refering to code in scikit-image and the policy / opinions of scikit-image devs about these issues.

Hi Stefan. In the near future I also want to implement Boykov-Kolmogorov and graph cuts. I think it would be nice to to GrabCut with sklearn+skimage. Let's see how this goes. Cheers, Andy Btw: I also like n**2 better but then my editor complains ;) On 06/15/2012 08:47 PM, StÃ¯Â¿Â½fan van der Walt wrote: > Hi Andreas > > On Fri, Jun 15, 2012 at 7:29 AM, Andreas Mueller > <amueller(a)ais.uni-bonn.de> wrote: >> I was wondering whether you are interested in having more image segmentation >> algorithms in skimage. > I am also very interested in matting algorithms and graph cuts, e.g.: > > http://www.inf.ufrgs.br/~eslgastal/SharedMatting/ > > StÃ¯Â¿Â½fan

SciPy2012 conference: Last week for early birds, poster submissions
by Stéfan van der Walt June 12, 2012

June 12, 2012

Hi everyone We're rapidly approaching SciPy2012 <http://conference.scipy.org/scipy2012>, which takes place in Austin, Texas from July 16th to 21st. This is a reminder that the *discounted early bird registration* closes on the 18th of this month. Also, we decided to keep the queue for *poster submissions* open until all slots are filled. So, whether you have a neat side project, a lightning talk gone rogue, or simply want to get the community talking about your latest and greatest idea--send in a poster abstract to 2012submissions(a)scipy.org. See you in Austin! Stéfan
