New plug-in

[Paul F Harrison]

Hello,

I have made a plug-in that does some interesting things, like applying
a theme taken from one image and applying it to another, or making an
image tilable. More details at

http://yoyo.cc.monash.edu.au/~pfh/fixer/

This is my first plug-in (and my first post to this list). Any comments
would be appreciated, especially about any GIMP conventions i may have
inadvertantly missed.

A question about patents. Is putting something on the web enough to
prevent someone patenting it, or could someone download my plug-in and
then patent the algorithm?

regards,
^^,
Paul Harrison

 Actually the first thing this plugin does is copy the pixel data into it's own
 process so there is no extra data thrashing going on (though it may be able to
 benefit from a call to gimp_tile_cache_ntiles).  Copying all the pixel info
 locally isn't exactly something that we should encourage plugins to do, but given
 the multipass nature of this plugin it seems a reasonable thing to do.
 
 The slow part of the plugin is finding the best matches between the input image
 and the corpus image.  I might suggest using a BSP tree or a multidimensional
 hash to speed that part of the process up, though I'm not sure if either of those
 would really be faster than the current qicksort like algorithm.  One other
 possible optimization would be to disregard duplicated patches from the corpus
 image.
 

Yep, the corpus search is what is slowing it down, my current algorithm is
pretty ugly -- a combination of a binary search tree and k-means.
Hopefully i can improve it for the next version.

btw, thanks to all the people who replied to my question about patents.
