You might have seen examples of Photoshop’s Content Aware Scaling feature in action, but do you know what goes on behind the scenes that allows it to magically work? This presentation from the SIGGRAPH 2007 conference sheds some light on the technical mojo that allows you to manipulate the size and shape of photos in crazy ways.
Liquid Scale is an app for the iPhone and iPod Touch that offers content aware image resizing. What does that mean? Basically it’s like a URL shortener for your photographs, reducing the dimensions of the photograph but retaining the meaning.
Liquid Scale enables new creative ways of editing images. It resizes pictures without deforming or cropping the content. Pictures can be transformed to a new aspect ratio in a fast and intuitive way.
Basically the application detects which areas of the photograph are “unimportant” (either automatically or manually), and attempts to only reduce and remove these areas through the resizing. Here’s an interesting video showing how it works:
We’re not sure how useful this app is, but the technology is pretty interesting nonetheless. The application is available at the iPhone App Store for $1.99.
