Phylogenetic Analysis of Multimedia Codec Software.

The phylogenetic analysis of multimedia contents (texts, images, videos and audio tracks) has been extensively investigated during the last years. Nevertheless, no research works have considered reconstructing the evolution and the dependencies among different releases of a given software. The current paper presents a first attempt in this direction considering different image and video codecs. The proposed solution codes a set of input images and videos, builds a dissimilarity matrix from the resulting coding artifacts, and then estimates the corresponding Software Phylogenetic Tree (SPT) using a minimum spanning tree algorithm. Experimental results show that the obtained accuracy is quite promising for different configurations.
