Abstract
The methods discussed so far have one common feature, they assign fixed-size codes to the symbols (characters or pixels) they operate on. In contrast, statistical methods use variable-size codes, with the shorter codes assigned to symbols or groups of symbols that appear more often in the data (have a higher probability of occurrence). Designers and implementors of variable-size codes have to deal with the two problems of (1) assigning codes that can be decoded unambiguously and (2) assigning codes with the minimum average size.
