In some instances, an image may have dimensions that do not correspond to a slot to display the image. For example, an image content item may have dimensions that do not correspond to a content item slot. The image may be resized using seam carving to add or remove pixels of the image. A saliency map for the image may be used having saliency scores for each pixel of the image. Evaluation metrics may be used before, during, and after, seam carving to determine whether salient content is affected by the seam carving. In some instances, a seam cost threshold value may be used for adaptive step size during the seam carving. The resized image may then be outputted, such as for an image content item to be served with a resource. |

1. A method for resizing an image comprising:
receiving, at one or more data processors, a request for a content item to be displayed with a resource; selecting, using one or more data processors, a content item comprising an image having a plurality of pixels; determining, by one or more data processors, a saliency score for each pixel of the plurality of pixels of the image, the saliency score for each pixel is based on at least one of:
a logo detection saliency value,a text detection saliency value, ora face detection saliency value; determining, by one or more data processors, a seam for the image based on the determined saliency scores; resizing, by one or more data processors, the image based on the seam; determining, by one or more data processors, a total cost value for the seam; and outputting display data to effect display of the resized image as the content item if the total cost value is below a minimum cost threshold value. |
