Rsizr

Rsizr narrowly avoids being a vowel-chopping online photo tool too far by doing something rather clever: re-sizing pictures intelligently using seam carving, a technique which attempts to keep intact the detailed parts of the image whilst stretching or squashing the less detailed parts.

Which allows you to do clever stuff like take a picture like this:



And expand out the background into something a little more panoramic:



You can see where the background has been widened, but it's less distorted than it would have been if you'd done a basic image stretch.

The application allows you to mark which parts of the picture you particularly want left unchanged, like the stunning creature on the beach in the above pic. Alternatively, if you'd like a bit less Becky in the world, you can mark which parts of the picture you want removed, which turns something like this:



Into this:



Note that the picture still includes the full width of the surroundings, but with 100% less Becky. Some people would pay good money for such a feature in real life.

Okay, so the results aren't flawless, but it's worth a play just to see the clever seam-carving algorithm working on-the-fly. Running it on a portrait picture is quite fun too, if a little disturbing. I'll spare you the results here and let you discover that for yourself!
