1. A method of automatic classification of images in an image collection comprising n images, comprising the following steps: classifying, according to user perception of resemblance, of transformed images in image sets, the transformed images being based on a same reference image, each of the transformed images having a distinct fingerprint distance with regard to the reference image; and determining of at least one fingerprint distance threshold that delimits the determined image sets within fingerprint distance zones; automatic classifying of the images in the image collection, comprising for each image i in the image collection, a determining of a fingerprint distance between said image i and each of other n-1 images in the image collection, and classifying said each of other n-1 images in one of said fingerprint distance zones according to the determined fingerprint distance.
