Rsizr - Free seam-carving image resizing on the web

E sent out a video explanation of  “seam carving” last week (awesome):

"At the SIGGRAPH 2007 conference in San Diego, two Israeli professors,
Shai Avidan and Ariel Shamir, have demonstrated a new method to shrink images.
The method is called 'Seam Carving for Content-Aware Image Resizing'
(PDF paper here) and it figures out which parts of an image are less significant.
 This makes it possible to change the aspect ratio of an image without making
the content look skewed or stretched out. There is a video demonstration up on YouTube."

So, thanks to E, the following caught my eye in the “Photo JoJo” e-newsletter:

Dr. Ariel Shamir and Dr. Shai Avidan describe their technique in detail. (Fun fact, Dr. Avidan was hired by Adobe shortly after this hit the web… look for seam carving to pop up in a future version of Photoshop!)
