Research
At the Institute of Communications Engineering, we investigate the interplay between multimedia signal processing, human perception, user experience and the sustainability of communication systems. We primarily analyse audiovisual systems along the entire transmission chain (recording, post-processing, coding, transmission, playback and optimization) to improve their quality and efficiency in operation and development. We consider aspects such as signal quality, perception, user behavior, cognitive performance, quality of experience and resource consumption, from energy to human resources such as fatigue, cognitive load or “cybersickness”. Our interdisciplinary research combines engineering, computer science, human-machine interaction and psychology. We pursue an open science approach for research that is as reproducible as possible and are closely networked with international partners from science and industry as well as spin-offs, for example from Prof. Raake’s predecessor institute at TU Ilmenau.
Point Cloud Coding
Point cloud coding describes the application of efficient algorithms for compression of point cloud data. The goal is to remove irrelevant or redundant content, in order to save the greatest possible data rate, whilst maintaining the best possible quality.
Main focus at the institute's work lies on signal interpolation between consecutive point cloud frames based on graph theory as well as the application of neural networks for efficient presentation (non-linear transforms) of single point cloud blocks.
