The dissimilarity between two objects determines how far apart they are with respect to each other. In this paper, Marina Oikawa, Zanoni Dias, Anderson Rocha and Siome Goldenstein provide an overview of the distance concept in multimedia phylogeny, a novel research field that aims at discovering the phylogenetic relationships among digital objects that belong to the same population.
With applications in digital forensics, copyright enforcement, and security, this paper presents a proper and well-designed dissimilarity approach, which is decisive for differentiating whether two multimedia objects are related and, also, the directionality of such relationship.
