Effective resizing of images should not only use geometric constraints,
but consider the image content as well. We present a simple
image operator called seam carving that supports content-aware
image resizing for both reduction and expansion. A seam is an optimal
8-connected path of pixels on a single image from top to bottom,
or left to right, where optimality is defined by an image energy
function. By repeatedly carving out or inserting seams in one direction
we can change the aspect ratio of an image. By applying these
operators in both directions we can retarget the image to a new size.
The selection and order of seams protect the content of the image,
as defined by the energy function. Seam carving can also be used
for image content enhancement and object removal. We support
various visual saliency measures for defining the energy of an image,
and can also include user input to guide the process. By storing
the order of seams in an image we create multi-size images, that are
able to continuously change in real time to fit a given size.
