1. A computer-implemented method for resizing an image using a seam carving algorithm, comprising: measuring, by a processor executing on a computing device, energy levels of pixels in an original image to derive an original energy map; applying, by the processor, a filter to the original energy map to derive a first energy map having quantities scaled different than the original energy map; iteratively applying, by the processor, the filter N times, starting with the first energy map, to an energy map resulting from an immediately preceding iteration; combining, by the processor, the resulting energy maps with the original energy map to form a composite image; and selectively deleting, by the processor, a seam from the original image using a seam carving algorithm with input from the composite image, thereby yielding a resized image.
