Research of the Coding and Visual Communication group

The overarching research theme of the Coding and Visual Communication group at DTU Fotonik is using coding technology to create efficient and secure communication and information systems for the future.

Coding for inspection of energy systems
Our image and video coding activities provide efficient visual communication technology as multimedia applications where a variety of image and video data need to be coded efficiently for optimal quality and the use of the available communication bandwidth or storage capacity.

Examples of research activities include drone imaging communication and multi-camera systems. The group covers selected topics of the full signal chain from capture to display.

The drone imaging projects are centered on inspection of energy systems as solar panels and district heating using infra-red imaging, supporting efficient green and sustainable energy systems for society.
Multi-camera systems can provide multi-view video and light-field images striving to reproduce visual scenes as close to real-life as possible. 

Coding for reliable networks and secure systems
Advanced error-correcting coding ensures reliable communication for wireless and optical communication and for both core and access networks. All present wireless systems apply error-correction and they would not function without.

In optical communication, forward-error-correcting coding (FEC) is a strategic discipline of increasing importance for high capacity long distance transmission. We are researching new methods for Terabit/second optical communication for Data Center Interconnects and core-systems, with bit error probabilities as low as 10-15 and better.

Finally, we use quantum technology to research in secure communication. Coding in Quantum Key Distribution (QKD) can provide and distribute provably secure keys for various forms of future cyber-systems, which is important because cyber wars and cybercrime are becoming a growing threat to society.
