Real-time data compression of broadcast video signals [PDF]

, 1990
A non-adaptive predictor, a nonuniform quantizer, and a multi-level Huffman coder are incorporated into a differential pulse code modulation system for coding and decoding broadcast video signals in real ...

Source Coding for Quasiarithmetic Penalties

, 2006
Huffman coding finds a prefix code that minimizes mean codeword length for a given probability distribution over a finite number of items. Campbell generalized the Huffman problem to a family of problems in which the goal is to minimize not mean codeword

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 ...

Entropy Coding Aided Adaptive Subcarrier-Index Modulated OFDM

IEEE Access, 2018
We propose entropy coding-aided adaptive subcarrier-index-modulated orthogonal frequency division multiplexing (SIM-OFDM). In conventional SIM-OFDM, the indices of the subcarriers activated are capable of conveying extra information. We propose the novel

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.

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响

Conservation Biology, EarlyView.
Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Running the Gauntlet: Experiences of Transgender and Gender‐Diverse People in the Recruitment Process

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.

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.
