My research activity has focused on the use of pattern recognition models for multimedia information retrieval and biometrics. Former studies targeted the definition of elastic models for measuring shape similarity and support shape based retrieval in image databases. From these studies, a number of different yet related topics were investigated, including image segmentation, content based description and retrieval of color images, multidimensional indexing structures for retrieval by color and shape, semantic content description in paintings and advertising videos, description and similarity matching of 3D models, segmentation of 3D models. Recently, my research activity focuses on the study of 3D data for person recognition and action recognition.
I serve as editor for Multimedia Systems and ACM Transactions on Multimedia Computing, Communications, and Applications (TOMM). I also serve as reviewer for many leading scientific journals including IEEE Trans. on Pattern Analysis and Machine Intelligence, IEEE Trans. on Multimedia, Neurocomputing and Pattern Recognition.
