Check out the original SIGGRAPH presentation on it. There are lots of really great demos. It's one thing to read about the algorithm, but to see it in action is magical.

This is still amazing all of these years later.

That... that was mind-blowing.

This discovery is 13 years old. Although it has clear limitations when it comes to humans, I'm surprised I don't see this kind of resize feature available in more software. Does Photoshop have this hidden in a drawer somewhere? Does imagemagick support this?

I seriously cannot decide if your post is satire. Directly from the wikipedia article:

http://www.imagemagick.org/Usage/resize/#liquid-rescale

Not at all. I have a pretty cursory knowledge of Photoshop and imagemagick (whenever I use either one I have to constantly google things).

Seam Carving is available in GIMP with the "Liquid Rescale" plugin.

$ apt install gimp-plugin-registry

Hmm, I knew it was implemented in a bunch of plugins or dedicated software like PS. However I am surprised it's not found all over the place by now as part of default apps / preview / OS builtin software / img tag options, etc.

Also none of the implementations I have tried (last time I checked, not up to date on this) were as slick / realtime / interactive as the SIGGRAPH demo.

You will probably see it appear everywhere in 10 years when the patent expires.

What prevents someone outside the US from using this?
