Within the THESEUS program, text and video restoration algorithms are being developed to achieve optimised digitisation results. The major challenge thereby consists in the automatic identification and correction of erroneous data. For instance, drop-out defects are detected and removed from digitised videos.

Within the THESEUS program, technologies for quality analysis of images and videos are being developed.  These technologies are capable to detect defects such as compression artifacts in images and videos. Furthermore, quality features such as sharpness and contrast of images or videos can be assessed. These hints are used for restoration or for retrieval of high-quality contents in multimedia databases.

Video signatures are, like human fingerprints, descriptions of a video that uniquely identify them. In contrast to cryptographic hashes, video signatures should be robust against modifications of the original video signal, such as text or logo overlay, recompression, scaling or camera-capturing.
Applications of video signatures include monitoring broadcast of TV ad spots, retrieval of duplicates in private video collections and internet video portals.

The 3D4YOU project will develop the key elements of a practical 3D television system, particularly, the definition of a 3D delivery format and guidelines for a 3D content creation process. The project generate 3D capture techniques, convert captured content for broadcasting and develop 3D coding for delivery via broadcast, i.e. suitable to transmit and make public. Its objective is to deliver an end-to-end system for 3D high quality media.                

The “Hardware Architectures and PCB Design“ group presents a data-processing platform based on FPGA (Field Programmable Gate Array) and optical interconnect technology. This enables the parallel and lossless transmission of high resolution high quality video streams in real-time over distances of up to ten kilometers.
