I think this post might be OT (that is OT for this thread).
'Content Aware Image Resizing"
http://www.youtube.com/watch?v=qadw0BRKeMkExtremely cool; One of the reasons I say this is it shrinks the picture by removing seams -- there is no decimation, so no intermediate colors are added, and this method tends to discern the important features of the image rather well. It breaks for some images that are just too 'full' already.
It seems to perform decently on pixel art, certainly well enough to save time. I chose some of the 'overworld' art from Flink and Lionheart as a stress test cause it's so detailed, and I must say it is pretty good even then at keeping the relevant detail and discarding the rest. (I did my tests using
Carlo Baldassi's implementation of CAIR for Gimp)
You should be aware that the more you shrink it, the more it's liable to effect the composition; after all, it works by gradually removing the 'insignificant spaces' in the picture.
My tests so far suggest that it's most useful for aspect ratio changes -- for example, resizing a wallpaper made for a laptop's wide screen to be suitable for a classic 4:3 display.
I haven't tried it for upscaling yet.... (update) have now. Doesn't appear very useful at all; maybe only for sparse photographs, not art.
EDIT: Probably it's best application is in texturing, to maximize the amount of 'meaningful' texture so the texture can be smaller.
