Last month we showed you an online demo of a super-cool image resizing algorithm. The demo was a bit rough around the edges, but showed how you could resize an image without making it look all distorted.

Now it looks like Rsizr has come pretty close to perfecting the process with a slick web-based application. All you have to do is upload a photo, push a few buttons, wait, wait, wait, and you can make your images larger or smaller without looking all squashed.

The site isn't as intuitive to use as we'd like. But after playing around a bit, here's what we can tell you. You have a choice of resizing your images the old fashioned way, or of using a seam carving algorithm that looks similar to the one co-developed by Shai Avidon who was recently hired by Adobe.

If you're okay with distorted looking images, just click the rescale tab for instant gratification. The retarget feature is where all the fun is at. First you tell Rsizr how many lines to scan and it will find "seams" of content that can be safely removed without making the image look funny. It will also figure out how to add lines if you want to stretch the image. In the video above you can see the difference between rescaling and retargeting. Very cool.
