Stefano Berretti is an Associate Professor at the Media Integration and Communication Center (MICC) and at the Department of Information Engineering (DINFO) of the University of Florence (UNIFI), Florence, Italy. His research interests are Computer Vision, Artificial Intelligence and Multimedia. During his Ph.D. and post-doc, he worked on image databases for effective and efficient image retrieval based on color, shape attributes, and spatial relationships. He also investigated the problem of retrieval from repositories distributed on the net using resource selection and results fusion. He provided several contributions on 3D object retrieval and partitioning, face biometrics (from 2D and 3D data), facial expression and emotion recognition (from 3D and 3D dynamic data), human action recognition from depth data, and 3D surface descriptors for relief patterns classification. He recently extended his interests to deep learning methods for face recognition and to their generalization to non-Euclidean domains (i.e., graphs, meshes, manifolds, etc.). He is a member of the Italian Association for "Computer Vision, Pattern Recognition and Machine Learning" (CVPL), previously known as "Group of Italian Researchers on Pattern Recognition" (GIRPR), affiliated to the International Association on Pattern Recognition (IAPR) of the Computer Vision Foundation (CVF) of ACM, Eurographics, and a senior member of the IEEE. He has been the Information Director of the ACM Transactions on Multimedia Computing, Communications, and Applications (ACM TOMM) and is now an Associate Editor for ACM TOMM, IEEE TCSVT, the IET Computer Vision journal, and the MDPI Sensors journal. He has also organized special issues of highly ranked journals (ACM TOMM, IEEE J-BHI, CAG Elsevier, IEEE TII) and served as editor of several books. He has been general chair, program chair, and area chair of several conferences and workshops.
