The aim of the sub project is to develop a source coding method for multimodal body envelope data that enables efficient transmission of the human body envelope including its motion. The spatial correlation of the depth signals, the temporal coherence of the human motion and the interconnection dependencies between microdoppler aperture synthesis radar data and depth signals are to be used for the coding. Depending on the reconstruction accuracy of the biomechanical and psychomotor applications in the CRC, a reduction of the data volume by at least two orders of magnitude is expected.
