The Multimedia Information Processing Systems Group was established in 2019 as a part of the Industrial Systems Institute of Athena Research Center. The group has active presence in signal processing and learning (adaptive filtering, numerical linear algebra in signal processing, sparse modeling and optimization, signal processing on graphs, accelerated deep learning), multimedia analysis and multimedia communications (3D/4D compression, denoising, completion, saliency map extraction, scalable rendering) interactive media (gesture identification, interaction in virtual environments, multimodal interaction)
