Identifying a photographer

摘要

A method of identifying a photographer includes determining a steadiness signal related to movement of a camera held by a first photographer while capturing an image or video, wherein the steadiness signal identifies the motion of the camera in at least two dimensions as a function of time and storing a set of steadiness signals where each steadiness signal has an associated known photographer. The method further includes using a processor to compare the steadiness signal to the set of steadiness signals to produce a set of similarity scores between the first photographer and each of the known photographers; and using the set of similarity scores to identify the photographer that has captured the image or video.
