Abstract
A system and method for performing content aware cropping/expansion may be applied to resize an image or to resize a selected object therein. An image object may be selected using an approximate bounding box of the object. The system may receive input indicating a lowest priority edge or corner of the image or object to be resized (e.g., using a drag operation). Respective energy values for some pixels of the image and/or of the object to be resized may be weighted based on their distance from the lowest priority edge/corner and/or on a cropping or expansion graph, and relative costs may be determined for seams of the image dependent on the energy values. Low cost seams may be removed or replicated in different portions of the image and/or the object to modify the image. The selected object may be resized using interpolated scaling and patched over the modified image.
