Abstract: A computer-implemented method executed by at least one processor for detecting tattoos on a human body is presented. The method includes inputting (701) a plurality of images into a tattoo detector, selecting (703) one or more images of the plurality of images including tattoos, extracting (705), via a feature extractor, tattoo feature vectors from the tattoos found in the one or more images of the plurality of images including tattoos, applying (707) a deep learning tattoo matching model to determine potential matches between the tattoo feature vectors and preexisting tattoo images stored in a tattoo training database, and generating (709) a similarity score between the tattoo feature vectors and one or more of the preexisting tattoo images stored in the tattoo training database.
