Reduction of Sufficient Number of Code Tables of $k$ -Bit Delay Decodable Codes

Kengo Hashimoto, Ken-ichi Iwata

A $k$ -bit delay decodable code-tuple is a lossless source code that can achieve a smaller average codeword length than Huffman codes by using a finite number of code tables and all…

Encoding and Decoding Algorithms of ANS Variants and Evaluation of Their Average Code Lengths

Hirosuke Yamamoto, Ken-ichi Iwata

Asymmetric Numeral Systems (ANS) proposed by Jarek Duda are high-performance distortionless data compression schemes that can achieve almost the same compression performance as ari…
