This has begun to appear on a few different websites and I thought that you maybe interested in this new way of resizing images without distorting the content. I'll let the author explain the details in the video (your going to be amazed for sure...!).
For those of you who are not mathematically challenged there's a whitepaper that explains the concept in detail.
The website is here and you can even upload a picture and try out the software online.
Apparently one of the authors has been recently employed by Adobe, so we may see this appear in future versions of Photoshop and/or Lightroom.
