abstract
Seam carving [Avidan and Shamir 2007; Rubinstein et al. 2009] revolutionized the way we think about image resizing by demonstrating that it is possible to obtain significant changes in image sizes with changes in proximity relationships, which we call topological properties of an image. Seam carving can change the size of an image by progressively carving out (or carving in) seams, which are monotonically connected paths of low-energy pixels crossing an image from top to bottom, or from left to right. Unfortunately, it quickly became obvious that seam carving creates geometric discontinuities once low-energy regions start to diminish. As a result, improvements and alternative approaches have been suggested to minimize discontinuities. 2012 ACM.
