An Early GSoC Purpose: Better nonlinear resampler for GEGL

Hi all,

I'm a student and interested in an GSoC idea: Better nonlinear resampler with built-in antialiasing (GEGL) suggested by Nicolas.

I have prepared to implement this idea for days, but today I found jungle had discussed this topic in January. .

I'm wondering whether jungle is a student and want to take part in GSoC 2009 too, if so, I think I have little chance to win because jungle looks more familiar with NEDI/ICBI than me. :)

Should I continue my preparation on this idea?

Thanks, Jenny

An Early GSoC Purpose: Better nonlinear resampler for GEGL

Hello Jenny:

Thank you very much for your interest in this project.

You unfortunately picked the one project for which I have someone in mind already. (This proves your good taste!)

I am double checking with this student that he wants this project as a GSoC. If so, he'll be my first choice for a variety of reasons, the main one being that he is working with me right now on "nohalo level 1," hence would be able to jump right into "nohalo level 2" and "snohalo level 1 and 2."

I'll let you know ASAP whether you should look "elsewhere."

(Note: all my other GSoC suggestions are "wide open" at this point.)

I have someone lined up for this particular GSoC project idea, so I suggest that you put your energy into another.

Best of luck,

Nicolas,

Thank you very much for your reply.

I'm a graduated student(Grade 1) majored in image processing and very interested in algorithms related to this field. I have prepared for this program (learning GEGL's code, searching papers on resampling algorithm, reading related code of matlab image processing toolbox, etc.)for days but it was so unfortunate.

It must be very helpful for me if you could suggest an idea which request familiar with image filtering algorithms. :)

Thanks, Jenny

Maybe

Fast Adaptive Resampler Tailored For Transformations Which Mostly Downsample (GEGL)

fits the bill? The prereq is understanding exact area box filtering (not a particularly deep filtering algorithm, I'll admit). The real hurdle is tweaking GEGL so that transformation information is passed on from operations which call on resamplers (or else, approximating it). That, I don't exactly know how to do, but I'm sure a kind (but busy, aren't we all?) soul within the developers' group would give us some guidance.
