Abstract :
One of the major challenges when applying (serial) universal source coding to 2-dimensional data, e.g., images, is to determine suitable context data. For this reason the concept of context mapping function (CMF) has been introduced. In this paper we discuss the foundation for CMF as well an off-line construction method via a combinatorial optimization method
