First Claim
Patent Images

1. A system, comprising:

  • one or more processors; and

    a memory coupled to the one or more processors and storing program instructions executable by the one or more processors to implement;

    in response to initiation of a single hybrid resizing operation to be performed on an image;

    accessing data representing the image;

    determining a respective energy value for each pixel of the image dependent on a value associated with each pixel;

    identifying a plurality of seams of the image having a cost below a configurable cost threshold whose value is specified for the single hybrid resizing operation, wherein the cost of each of the identified seams is dependent on the respective energy values of pixels of the seam;

    performing a resizing operation on the image along the plurality of identified seams to produce a resized version of the image, wherein said performing comprises applying a seam carving technique; and

    applying a scaling technique to at least a portion of the resized version of the image to produce a further resized version of the image.
