A Faster Arithmetic Coder

Arithmetic coding is a highly effective method for data compression. One of the criticisms levelled at it is that it runs fairly slowly. We propose a novel method for arithmetic coding that runs at a significantly higher speed and can be implemented using simple hardware if required.

A Mixed-Framework Arithmetic Coder

A mixed-framework adaptive arithmetic coding technique is introduced in which the probability estimation process dynamically switches among a set of allowed models; the sequence of model choices is determined jointly with the relative data segmen-tation to yield the optimal coding performance for the given set of predictors. A speciic application is detailed in which the arithmetic coder can sw...

Subband Coding of Color Images with Dynamic Arithmetic Coder Allocation

This paper presents a subband coder for compression of color still images. The red, green, and blue (RGB) color components are rst transformed to a luminance-chrominance representation , and then each of the three image components are decomposed by an FIR analysis lter bank. The two chrominance components are decimated by a factor of 10:1 or 20:1, depending on the bit rate. The coder is based o...

An Adaptive Binary Arithmetic Coder Using a State Transition Table

We propose a fast and simple binary arithmetic coder, STT-coder, in which arithmetic operation of dividing the probability interval can be done using a state transition table. In order to simplify the state transition table by omitting to retain the both of the bottom address of the valid interval and renormalized interval, renormalization is mostly executed together with the flush operation of...

A highly efficient multiplication-free binary arithmetic coder and its application in video coding

A novel and highly efficient algorithm of multiplicationfree binary arithmetic coding is proposed. Our proposed method relies on simple table lookups for performing the computationally critical operations of interval subdivision and probability estimation. Moreover, the underlying design principle provides a great flexibility for serving the different needs of all kind of coding applications wh...
