The reasons for compressing digital information are to save storage space and transmission bandwidth. Particularly high compression rates can be achieved with lossy methods. This takes advantage of the fact that a large part of the data presented is not absorbed by the human user. In the training course, the mathematical principles of lossy compression of image, sound and video data will be explained using popular examples (keywords: jpeg, mp3, mpeg) and algorithms for fast calculation will be discussed.
