“Content-Aware” Smart Image Resizing Algo

Everyone who has ever worked with digital images know that you resize an image either by cropping it (and potentially lose important parts of the image) or shrinking it (and lose size or contend with a distorted image).

Ariel Shamir of the Efi Arazi School of Computer Science in Herzliya, Israel, shows us another way: content-aware "smart" image sizing, where you can have your "image cake" and eat it too (you’ll see what I mean):

Retargeting is a new technology focused on solving problems with changing sizesof digital photography, while traditional crops often fails to include all elements and resize may make the image too small to distinguish, retargeting, using an algorithm, recognizes what’s relevant to the image, and column by column of pixels are removed.

As a webdesigner and self-taught graphic artist, I have to say that is outstanding and pretty darn amazing! Hopefully an open-sourced or adobe plug/patch will be released for photoshop!

That’s pretty crazy. I wonder if it requires a new format or if it can be adapted to existing Web formats such as PNG.

I really like that, especially the ‘erasing.’

It looks amazing from the demo. My concern is that it demands that the algorithm _knows_ what are the important features of a picture.

I’m eager to try this on one of my random picture and see how it performs.

Hi,
If you are looking for a software to try out seam carving, take a look at http://www.thegedanken.com/retarget

The program that you can download there (for Windows and Linux, and free) is already highly optimized concerning speed, and apart from enlarging or decreasing image size you can also use masks to protect or delete certain parts of your image.

Have fun,
Irmgard

Check out rsizr.com for a free Flash-based implementation of seam carving that lets you resize your own images, both in height and width simultaneously, in real time. (You can rescale and crop images too!)
