Neural network-based arithmetic coding of intra prediction modes in HEVC
, 2017 In both H.264 and HEVC, context-adaptive binary arithmetic coding (CABAC) is adopted as the entropy coding method. CABAC relies on manually designed binarization processes as well as handcrafted context models, which may restrict the compression ...

Enabling error-resilient internet broadcasting using motion compensated spatial partitioning and packet FEC for the dirac video codec [PDF]
, 2008 Video transmission over the wireless or wired network require protection from channel errors since compressed video bitstreams are very sensitive to transmission errors because of the use of predictive coding and variable length coding. In this paper, a

Arithmetic Coding for Data Compression [PDF]
Proceedings of the IEEE, 1994 Arithmetic coding provides an effective mechanism for removing redundancy in the encoding of data. We show how arithmetic coding works and describe an efficient implementation that uses table lookup as a first alternative to arithmetic operations. The reduced-precision arithmetic has a provably negligible effect on the amount of compression achieved ...

Secure FSM-based arithmetic codes [PDF]
Signal, Image and Video Processing, 2012 Recently, arithmetic coding has attracted the attention of many scholars because of its high compression capability. Accordingly, in this paper a method which adds secrecy to this well-known source code is proposed. Finite state arithmetic code (FSAC) is used as source code to add security.

Soft and Joint Source-Channel Decoding of Quasi-Arithmetic Codes
EURASIP Journal on Advances in Signal Processing, 2004 The issue of robust and joint source-channel decoding of quasi-arithmetic codes is addressed. Quasi-arithmetic coding is a reduced precision and complexity implementation of arithmetic coding. This amounts to approximating the distribution of the source.

Adaptation of Zerotrees Using Signed Binary Digit Representations for 3D Image Coding [PDF]
, 2007 Zerotrees of wavelet coefficients have shown a good adaptability for the compression of three-dimensional images. EZW, the original algorithm using zerotree, shows good performance and was successfully adapted to 3D image compression.
