Perceptually-driven video coding with the Daala video codec [PDF]
SPIE Proceedings, 2016 The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR.

VcLLM: Video Codecs are Secretly Tensor Codecs
CoRRAs the parameter size of large language models (LLMs) continues to expand, the need for a large memory footprint and high communication bandwidth have become significant bottlenecks for the training and inference of LLMs. To mitigate these bottlenecks, various tensor compression techniques have been proposed to reduce the data size, thereby alleviating

Deep blueprint: A literature review and guide to automated image classification for ecologists
Journal of Animal Ecology, EarlyView.A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Video data recovery from slack space of pre‐allocated video files
Journal of Forensic Sciences, EarlyView.Abstract The recovery of video evidence from dashboard cameras is often compromised by damage, file system errors, or circular recording mechanisms that overwrite older data. Traditional digital forensic techniques primarily focus on file carving and frame recovery from the unallocated area of storage media. However, this approach is often insufficient

A COMPARATIVE ANALYSIS BETWEEN DIRAC, H.264 AND HEVC VIDEO ENCODERS AT VARIABLE BIT RATES
Electrica, 2016 This work presents a comparative analysis of Dirac, H.264 and HEVC video codecs. Encoding file sizes, Peak Signal to Noise Ratio (PSNR), Structural Similarity Index Metric (SSIM) measurements and encoding times are compared.

Image‐Based Spatio‐Temporal Interpolation for Split Rendering
Computer Graphics Forum, EarlyView.Abstract Low‐powered devices – such as small form factor head‐mounted displays (HMDs) – struggle to deliver a smooth and high‐quality viewing experience, due to their limited power and rendering capabilities. Cloud rendering attempts to solve the quality issue, but leads to prohibitive latency and bandwidth requirements, hindering use with HMDs over ...

Sensors, 2022 The paper proposes a novel post-filtering method based on convolutional neural networks (CNNs) for quality enhancement of RGB/grayscale images and video sequences. The lossy images are encoded using common image codecs, such as JPEG and JPEG2000.

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.ABSTRACT Computational mechanics is inherently complex, as the underlying physical processes evolve in three spatial dimensions and time. Thus, intuitive visualizations in traditional lecture notes or on blackboards are challenging. This motivates the use of animation software to illustrate time‐dependent three‐dimensional phenomena, which complement ...
