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 seam of the image having a lowest cost, wherein the cost of the seam is dependent on the respective energy values of pixels of the seam;

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

    repeating said identifying and said performing for a next lowest cost seam until a specified portion of the single hybrid resizing operation for the image is achieved by the resized version of the image; 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.
