Learning outcomes

The student learns the basics of information theory, some well-known source encoding methods, and their application in data compression.


In source encoding we devise schemes which minimize the number of bits in a message without losing any of its information content. Well-known examples of these techniques are Huffman and arithmetic codes. Because the methods can be applied only when we have a good model of the source, we study also different modelling techniques, especially predictive and dictionary approaches. In the latter part of the course we put this theory into practice with an overview of various compression methods for text and images.
