Hi everyone,
My name is Rafael, I am an Brazilian student of Computer Engineering from
Universidade de Pernambuco and about one year ago i have been studying image
processing, so i become interested in working in an gimp project.
People usually want to process image for specifics reasons : noise
extractions, signatures analysis, historic documents analysis, activation
areas detection from an human brain studies, and for so many other reasons.
In addition to this, those images can be of n different types. My general
idea is to make a plugin to help people doing new Filters, for their
specific reasons, without the need of writing new code. The idea consists on
creating those filters from basic Morphologic Operators (dilate, erode,
opening, closing and morphological gradient) and , in the future, creating
new filters based on other filters (combining them).
I know that gimp already works with Dilate and Erode operations, but it does
not give the possibility of creating new structuring elements for those
operands (dilating an image with a cross 13x13 can be much better than doing
it with a circle 3x3, depending on the user´s need) and neither of
combining them with other operations.
There is something similar to what i want to do, in an ImageJ Plugin (
http://svg.dmi.unict.it/iplab/imagej/Plugins/Morphological%20Operators/Morphological%20Operators/MorphologicalOperatorsPlugin.htm-
here you can see an image from the interface of Morphological
Operators
plugin that can help you to understand my idea). I usually work with this
tool and i think it is very useful, but it can`t save operators made by user
to combine them with other operations in the future.
Well, i am waiting a feedback from you. Suggestions/Critics ? is this idea interesting/relevant for gimp ?
you can found me on #gimp -> Galva and msn -> rgalvaomesquita@msn.com.
Thank you very much for your attention :),

Hi Rafael, thanks for introducing yourself. Your ideas are quite sophisticated, but I don't have a clear picture of who would use this capability, or what they would use it to do. Could you explain a little more, please?

Hi,
this sounds like an interesting project, but it is very much directed towards scientific image processing which seems quite out-of-scope for GIMP. Of course such a plug-in could be written and it would be a nice addition for a very special and very small user group. But I don't think it would be of interest for our main user base. Of course, if we can find a mentor for it, it could still be a GSoC project. I don't think it would get high priority though.

Hi Rafael,
your idea sounds interesting, and would definitely be a great tool for ImageJ, but I'm not sure it is very relevant for The GIMP, which is mainly targeted at interactive image manipulation, as opposed to the batch processing one usually does in image processing applications of the sort you describe.
If you are currently using ImageJ, what would you say is the advantage of doing it in The GIMP, instead of a GUI on top of ImageJ? ImageJ has all the relevant operations already, so I would expect that to be much less work.
cheers,

Bill ,
like Sven said, my idea is directed towards scientific image processing, but
I think this doesn`t mean only few people would use it, maybe this could
help gimp developer`s too, for example.
Sven, I understand your point, and agree with most things that you said.
Ingo, it really would be much less work, but the work would not be only doing a GUI for imageJ. the advantage of doing it on The Gimp is that The Gimp is a much bigger project, than imageJ and it could have those interesting tools.
Well, If you change your mind and decide to go ahead with this, or any similar idea, please contact me, i am disposed to talk.
thank you for your attention, again

That isn't quite how GSOC works. Students apply, then people from the project rank their proposals. Google looks at the rankings and decides which projects to support. We're just letting you know that some of us are not disposed to give such a project a very high ranking unless you can do more to convince us that the results would be used by numerous people to do important things.
Best wishes,

If the goal is to write filters suitable for scientific processing I
would think it makes sense
to implement the filters for GEGL instead of GIMP, since GEGL operates
with 32bit floating
point buffers. Combining operations in GEGL to create new combined ops
is something that already is possible, but needs further work (it is
currently hard-coded in C while it should be done using an XML based
format or similar (as well as have a usable UI.).
