Re: best image enlargement process/ algorithm?

Just wondering what is now considered the best image enlargement algorithm

the normal bucubic doesn't do a whole lot.

It might well be "greycstoration" -- google for that, or:

There are several modes for use of this algorithm, including
resizing (which it does at least as well as cubic interpolation)
and "inpainting" -- trying to smoothly reconstruct missing
portions of an image, as from bad pixels. It's being
used in at least the latter sense by someone working
on the Chandra project, who mentioned it on the astro-viz
mailing list recently.

The "demonstrations" section on the page is pretty impressive.

being pretty impressed by it)
