Thanks for the insight and ideas. I didn't mention I am working on a numerical algorithm for deblurring images that have been blurred by non-accelerated circular motion around any possible axis so it was nice to get some ideas however the applications for which it is intended require more accuracy. I also noticed that this particular filter is quite slow.
I have been experimenting with deforming the image into polar coordinates using interpolation schemes to get a good resolution and then applying regular, linear motion blur horizontally or vertically which would correspond to the "zoom" blur or "rotational" motion blur effects. Then the image must be deformed back to cartesian coordinates using again some sort of interpolation. So far it looks right if resolution is taken care of and it's quite fast. Haven't tried the cases where the image plane is not perpendicular to the axis of rotation and the debluring algorithm still needs to be developed. In any case all this is in prototype form (Matlab) and if all goes well it could be perhaps ported to GIMP when everything has been worked out. _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
