Multimodal Quality Assessment on Videoconferencing


Benjamin was born in France in 1983. He first studied general Mathematics and Physics in Toulouse. Then he joined the National School of Higher Education in Physics of Strasbourg (Engineering school) and specialized in Video and Image Processing. He carried out his master's degree within the INRIA in cooperation with the LIAMA (Beijing) on "Structural Change Detectection on Satellite Images using Conditional Mixed States Markovian Model". In 2007, he started a Phd within the Deutsche Telekom Laboratories and the Technical University of  Berlin.
