What is the image-resizing technique that reduces width by removing low-detail paths?

I’m trying to identify a retouching/resizing method that can make an image narrower without simple stretching or ordinary cropping. As I remember it, the algorithm finds low-contrast or low-detail paths running through the image and removes them one by one, so well-defined subjects are mostly preserved while less important areas shrink. What is this technique called, and are there common implementations of it?

It seems to be called Seam Carving, and the Gimp has this feature as Liquid Rescale. You're right -- it collapses out parts of the image with less detail where you won't notice it. Liquid Rescale also has options to mask parts of the image you want to preserve and parts you want to eliminate. There's a great demo in Episode 14 of Meet the Gimp

This technique is called seam carving (also known in some software as content-aware resizing). It works by finding low-energy paths—areas with less visual detail or contrast—through the image and removing them, which can reduce width or height while preserving important subjects better than normal scaling.
A commonly cited implementation is Liquid Rescale in GIMP. It can resize images this way and may also let you protect areas you want preserved or prioritize areas you want removed.
