Construction of Almost Instantaneous FV codes based on Integer Programming

Abstract (in Japanese) (See Japanese page) 
(in English) The Almost Instantaneous FV (AIFV) code, which consists of
several code trees with incomplete internal nodes, can attain
better compression rate than the Huffman code. Although the AIFV code trees can be constructed by a greedy algorithm considering costs defined for the number of children of incomplete internal nodes, the obtained AIFV code is not always optimal. In this paper, we show that for given costs, the optimal AIFV code can be derived by solving an integer programming problem. Furthermore, we can derive a better AIFV code by iterating the construction of the optimal code trees for given costs and the cost updating for given code trees. Finally, the performance of our constructed AIFV codes are evaluated numerically for several source models.
