Arithmetic Coding (AC) is widely used for the entropy coding of text and multimedia data. It involves recursive partitioning of the range [0,1) in accordance with the relative probabilities of occurrence of the input symbols. In this work, we present a d

data compression is concerned with encoding the data in a way that makes use of probability estimates of the events. Lossless compression has the property that the input sequence can be reconstructed exactly from the encoded sequence. Arithmetic coding is a nearly optimal statistical coding technique...

Khalid Sayood, in Introduction to Data Compression (Fifth Edition), 2018 4.9 Summary In this chapter, we introduced the basic ideas behind arithmetic coding. We have shown that the arithmetic code is a uniquely decodable code that provides a rate close to the entropy for long stationary sequence...
需要注意的是,Arithmetic coding算法需要知道数据的统计特性(如平均数、方差等),以便正确解码。因此,在使用Arithmetic coding算法之前,通常需要先对数据进行预处理,例如计算均值和方差。Arithmetic coding algorithm in python along with statistical data compression models like ppm, context mixing, etc.点...
