Aránzazu Jurío-Munárriz was working with an infographics company on creating “super resolution” images, and along the way came up with a way to resample and magnify images that’s 700-times faster than traditional methods.
Starting with a three-dimensional model the company used to generate various images to show to its clients; these images needed to be large so that all the details could be appreciated, but generating them took over 20 hours per image. “The solution we found meant that images could be generated in a smaller size and then enlarged in a very short space of time (less than one hour per image) while maintaining quality.
I’ve been looking around, trying to find the paper referenced for more information, but I can’t find it. If you find it, post it in the comments below.

It does contain a number of papers (though few are well-cited) that include image magnification methods.
