Side Information Generation Scheme Based on Coefficient Matrix Improvement Model in Transform Domain Distributed Video Coding

open access: yesEntropy, 2020
In order to effectively improve the quality of side information in distributed video coding, we propose a side information generation scheme based on a coefficient matrix improvement model. The discrete cosine transform coefficient bands of the Wyner–Ziv

Neural network-based arithmetic coding of intra prediction modes in HEVC

open access: yes, 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 ...

How and Why Do Number-Space Associations Co-Vary in Implicit and Explicit Magnitude Processing Tasks?

open access: yesJournal of Numerical Cognition, 2017
Evidence for number-space associations in implicit and explicit magnitude processing tasks comes from the parity and magnitude SNARC effect respectively.

Fast and Efficient Entropy Coding Architectures for Massive Data Compression

open access: yesTechnologies, 2023
The compression of data is fundamental to alleviating the costs of transmitting and storing massive datasets employed in myriad fields of our society. Most compression systems employ an entropy coder in their coding pipeline to remove the redundancy of ...

Enabling error-resilient internet broadcasting using motion compensated spatial partitioning and packet FEC for the dirac video codec [PDF]

open access: yes, 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

Secure FSM-based arithmetic codes [PDF]

open access: yesSignal, 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

open access: yesEURASIP 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.

Thermometer Code Based Modular Arithmetic [PDF]

open access: yes2012 Spring Congress on Engineering and Technology, 2012
This paper presents a novel approach to perform modular arithmetic addition and subtraction using base-1 thermometer code data format for operands corresponding to the residues of the same modulus. Two n-bit thermometer code operands are first concatenated and logically shifted to produce a normalized 2n-bit thermometer code intermediate sum.
