چکیده
We present the Z Coder a new adaptive data compression coder for coding binary data The Z Coder is derived from the Golomb run length coder and retains most of the speed and simplicity of the earlier coder The Z Coder can also be thought of as a multiplication free approximate arithmetic coder showing the close relationship between run length coding and arithmetic cod ing The Z Coder improves upon existing arithmetic coders by its speed and its principled design In this paper we present a derivation of the Z Coder as well as details of the construction of its adaptive probability estimation table

An Efficient Adaptive Binary Arithmetic Coder and Its Application in Video Coding
Adaptive Binary Arithmetic coding is an effective mode of coding. In this paper we propose an efficient adaptive binary arithmetic coder, which is multiplication-free and look-up table free. To achieve this, we combine the probability estimation based on the virtual sliding window technique with the approximation of multiplication and the use of simple operations to calculate the next approxima...

متن کاملAn 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...

In this paper we propose a novel efficient adaptive binary arithmetic coder which is multiplication-free and requires no look-up tables. To achieve this, we combine the probability estimation based on a virtual sliding window with the approximation of multiplication and the use of simple operations to calculate the next approximation after the encoding of each binary symbol. We show that in com...
متن کاملAdaptive Binary Arithmetic Coder-Based Image Feature and Segmentation in the Compressed Domain
Image compression is necessary in various applications, especially for efficient transmission over a band-limited channel. It is thus desirable to be able to segment an image in the compressed domain directly such that the burden of decompressing computation can be avoided. Motivated by the adaptive binary arithmetic coder MQ coder of JPEG2000, we propose an efficient scheme to segment the feat...
