[Gimp-developer] PatchMatch
I'm not sure if this is the right place to post this since I'm pretty new to the open source community. However, did anyone ever look into implementing the PatchMatch algorithm in GIMP? There's a video on it at http://www.youtube.com/watch?v=dgKjs8ZjQNg and a paper at http://www.cs.princeton.edu/gfx/pubs/Barnes_2009_PAR/index.php with sample source code. It seems like a major step in image editing and there's no program that fully uses it yet. Supposedly Adobe Photoshop CS5 included some parts of it for context-aware filling but most features aren't implemented. If we could port it to GIMP, I'm sure there could be a huge variety of applications and many users would switch for that feature alone. - Andrey ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

[Gimp-developer] Optimized Despeckle plug-in
Hi, As a part of my student project for Optimizing Open-Source Applications at Warsaw University I have speed up despeckle plug-in for gimp. Original version of the plugin run 56seconds for 1024x768 image with despeckle radius 30 and adaptive flag turned off (on my Intel Macbook 2.1GHz). My optimized version with the same settings completes the task in 3.5 seconds with the same image quality :-) Sources for this optimized plug-in can be downloaded from here: http://students.mimuw.edu.pl/~pz248275/despeckle.chttp://students.mimuw.edu.pl/%7Epz248275/despeckle.c What should I do to get this to the gimp repository? Should I change the copyright header? Thanks, Przemyslaw Zych ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Should I change the copyright header? Hi! That sounds great. To maximize chances of getting this into GIMP: 1. Create a regression test for the despecle plug-in that is run with 'make check'. This is a great way to convince us that your optimization in fact does not change the output, only improves performance. 2. Create a patch, following the instructions here: http://www.gimp.org/bugs/howtos/submit-patch.html Since your change is significant, feel free to add yourself to the copyright header.

[Gimp-developer] About Gimp Icons license
Hello! Yesterday I suggest Pinta developers (http://pinta-project.com/) improve this nice software using the Art Libre Set icons. There are a problem: Art Libre Set is under GPL License and it appears to be incompatible with MIT License (The one Pinta uses). I asked to the Tango mailing list and someone tell me the Gimp Icons are under LGPL, then they could be used. But I can not find any reference where appears that Gimp icons are LGPL. ¿Are the Gimp tools and menu Icons under the GPL or LGPL license? ¿Could be the icons used for Pinta? The Art Libre set allow graphical applications to be easy to use for people (same tools work similar way) and I think Pinta could be improved using it.

This is a great way to convince us that your optimization in fact does not change the output, only improves performance. Well, as far as I can see the current implementation of the despeckle plug-in does not match the expectations. IMO it is buggy. Thus we should not absolutely require that the result does not change. But it would be desirable to get fixes to the algorithm submitted separately from optimizations. It would also help a lot if the patch followed the GIMP coding style.

If you code produces the same kind of results with that much of a speed increase a patch would be worth providing. Kudos for achieving that level of speed up. I guess by now you must have got a good feel for the way that part of the code base works so if you can write a despeckle routing that does despeckle that would be a worthwhile contribution as well. Thanks for you efforts. /gg ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

If you code produces the same kind of results with that much of a speed increase a patch would be worth providing. Kudos for achieving that level of speed up. The quality of results also very much depends on how the parameters are chosen. A speedup of the algorithm will make it easier to experiment with the parameters as it should also speed up the preview significantly. So yes, we should try to get that patch into GIMP as soon as possible.
