The Signal Processing for Media Applications (Sigmedia) Group is a research group in the Department of Electronic and Electrical Engineering at Trinity College Dublin.
Research
We explore problems that involve visual or audio digital media. Evolving from expertise in digital signal processing, we create solutions based on a healthy mix of statistics, probabilistic inference, applied mathematics, and human perception. The team operates in well-recognised domains: computer vision, audio/video processing, and speech and language understanding. There are four main themes:
Human Speech Communication
Modeling multimodal interactions, speech recognition, and synthesis using deep learning and human perception.
Computational Acoustics & Spatial Audio
Advanced audio signal processing for room acoustics, spatial audio rendering, and immersive soundscapes.
Media Compression & Streaming
Optimizing video and audio pipelines for ultra-low latency streaming and efficient cloud processing.
Digital Cinema & Restoration
Award-winning research in motion picture enhancement, archival restoration, and high-end visual effects.
Current Research Projects & Topics
Audio
- • Multi-modal Turn-taking Prediction
- • Low-Resource Speech Recognition
- • Speech Model Distillation
- • Linguistics & Speech AI
Video
- • Efficient Image Denoising
- • Video Compression Pipelines
- • Motion Picture Enhancement

We are well known for our work on cinema post-production. Our motion and visual enhancement technologies (in collaboration with Foundry) were used around the world for film post production in movies like The Matrix, Lord of the Rings, X-Men, Spider-Man, and Harry Potter. This work was recognised by the Academy of Motion Picture Arts and Sciences in 2007 with a Scientific and Engineering Oscar award.
Collaboration
We have collaborated closely with Industry and many EU projects involving archives and broadcasters around Europe. Our current projects are funded by the European Union, Science Foundation Ireland, IRCSET, and Enterprise Ireland.
