The Coding and Visual Communication Technology Group focuses on error-correcting coding and image and video coding.
Error-correcting coding
Advanced error-correcting coding is useful for both core and access networks. Applications in radio and satellite communication have been the most important for many years. All present wireless systems apply error-correction and they would not be possible without. In optical communication, it is becoming a strategic discipline for high capacity transmission where new codes will be tailored to the properties of the transmission line. The research here is focused within the following main activities:
- decoding algorithms - implementation
- coding and transmission systems suited for iterative decoding/reception
- application of coded systems in satellite communication
- application of error-correcting coding in optical communication
Image and video coding
The image and video coding activities are directed towards multimedia applications where a variety of image and video data need to be coded efficiently for optimal use of the available communication bandwidth. The transmission of video and visual data in general is often a driving force for new broadband systems. Examples of research acitivities within the group are:
-
improving video quality for LED backlit flat panel displays
-
-
video in broadband networks
-
error resilient video coding for wireless communication including satellite
- video and image coding for space applications
- two-dimensional information theory
- multiview image and video coding
The group has recently received founding from the Danish Research Council (FTP) for a project on distributed video coding and processing. More information is found
