Data Compression Applications

The application of data compression in the graphic arts is usually used for the storage or transmission of digitized image data, for the conservation of storage capacity or transmission time. data compression can be achieved by using techniques derived from information theory, by dividing the information into four parts. These four parts are components of known (redundant), or unknown (non-redundant), or relevant (of interest) or irrelevant (of no interest) information. It can be deduced that only those information components which are non-redundant and of interest to the recipient must be stored or transmitted. In the application of data compression, the best results are derived by removing all redundant components and as many irrelevant components as possible.
