1. A method of image retargeting, the method comprising:
obtaining a source image;
obtaining a target size for a retargeted image based on the source image;
generating a two-dimensional importance map for the source image;
generating, based on the two-dimensional importance map and the target size, a warping mesh having a distortion metric below a threshold value;
determining whether a size of the warping mesh corresponds to the target size;
based on the size of the warping mesh being determined to correspond to the target size, rendering the retargeted image by applying the warping mesh to the source image, and
based on the size of the warping mesh being determined to not correspond to the target size:
generating, based on the warping mesh, a cropped warping mesh comprising at least one cropped region based on a one-dimensional version of the two-dimensional importance map, and
applying the cropped warping mesh to the source image to render the retargeted image.
