rsizr – Intelligent Image Resizing
http://rsizr.com/

rsizr is a free Flash application that lets you resize JPG, PNG, and GIF images on your computer. With rsizr, in addition to normal image rescaling and cropping, you can also resize images using a new image resizing algorithm called seam carving (a method of image retargeting) that tries to keep intact areas in your image that are richer in detail. Seam carving is a brilliant image resizing technique pioneered by Shai Avidan and Ariel Shamir. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
