1. A computer-implemented method, comprising: determining a reference set of values of image features characterizing a cropping reference; ascertaining a candidate area of an image as a candidate for inclusion in an area to be cropped; generating a candidate set of values of the image features characterizing the candidate area; adding the candidate area to the area to be cropped based on a determination that a distance between the reference set of image feature values and the candidate set of image features values satisfies a condition; selecting another area of the image as the candidate area; repeating the generating, the adding, and the selecting; and cropping the area to be cropped from the image to produce a cropped image.
