Huffman coding with unequal letter costs [PDF]
Proceedings of the thiry-fourth annual ACM symposium on Theory of computing - STOC '02, 2002 (MATH) In the standard Huffman coding problem, one is given a set of words and for each word a positive frequency. The goal is to encode each word w as a codeword c(w) over a given alphabet. The encoding must be prefix free (no codeword is a prefix of any other) and should minimize the weighted average codeword size Σw freq w, |c(w)|. The problem has a

Variable‐Rate Texture Compression: Real‐Time Rendering with JPEG
Computer Graphics Forum, EarlyView.Abstract Although variable‐rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real‐time rendering due to special requirements such as random access to individual texels. In this paper, we investigate the feasibility of variable‐rate texture compression on modern GPUs using the ...

Modified HuffBit Compress Algorithm – An Application of R
Journal of Integrative Bioinformatics, 2018 The databases of genomic sequences are growing at an explicative rate because of the increasing growth of living organisms. Compressing deoxyribonucleic acid (DNA) sequences is a momentous task as the databases are getting closest to its threshold ...

NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields
Computer Graphics Forum, EarlyView.Abstract Achieving realistic rendering of 3D scenes in real time using path tracing is challenging due to the high sample count required, with ray tracing as the bottleneck. Focusing on voxels as a geometry representation offers significant opportunities for optimizations, especially for tracing the rays, but also for computing the samples.

It's Been 1,000,000 Years since Huffman [PDF]
, 2015 Huffman codes are legendary in the computing disciplines, and are embedded in a wide range of critically important communications and storage codecs. With 2015 marking the 64th anniversary of their development −1,000,000 years in binary -it is timely to ...

Tradeoff Between Speed and Memory Requirements for Decoding of Prefix-Free Codes
AlgorithmsFor the decoding of prefix-free codes such as Huffman code, we present a tradeoff between the decoding speed and memory requirements that results in an adapted decoding algorithm.

Gender, Work &Organization, EarlyView.ABSTRACT This study focuses on the recruitment experiences of transgender and gender‐diverse (T&GD) individuals. Reporting on semi‐structured interviews with 22 T&GD individuals from Australia, the study suggests critical moments occur during the recruitment process for T&GD candidates, contributing to both theory and practice.

Algorithmic counting of nonequivalent compact Huffman codes
, 2023 It is known that the following five counting problems lead to the same integer sequence~$f_t(n)$: the number of nonequivalent compact Huffman codes of length~$n$ over an alphabet of $t$ letters, the number of `nonequivalent\u27 canonical rooted $t$-ary ...

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.

Early Labor Market Outcomes of Young Adults From Same‐Sex Families: Evidence From Population Data
Journal of Marriage and Family, EarlyView.ABSTRACT Objective This study offers the first population‐based evidence on how young adults from same‐sex families fare when entering the labor market shortly after leaving full‐time education. Background Same‐sex couples' parenting rights remain controversial in many countries.
