ADAPTIVE THREE-DIMENSIONAL DISCRETE COSINE TRANSFORM OF TRANSPORT IMAGES [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2019 Subject of Research. The paper presents encoding and decoding method for video information obtained from video surveillance cameras in transport. The method is based on the usage of adaptive three-dimensional discrete cosine transform.

LLM‐based keyword augmentation for title‐driven evidence selection: A practical approach
Journal of Forensic Sciences, EarlyView.Abstract Keyword‐based search is widely used in digital forensic investigations, yet its effectiveness depends strongly on investigator experience, leading to inconsistent results and missed evidence. While previous studies have explored machine learning and large language models (LLMs) to address this, practical deployment is often constrained by ...

Rtp and the datagram congestion control protocol [PDF]
, 2006 We describe how the new Datagram Congestion Control Protocol (DCCP) can be used as a bearer for the Real-time Transport Protocol (RTP) to provide a congestion controlled basis for networked multimedia applications.

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 ...

Fixed-rate video codecs for wireless systems [PDF]
Proceedings of First International Workshop on Wireless Image/Video Communications, 2002 A comparative study of arbitrarily programmable, but fixed-rate videophone codecs using quarter common intermediate format (QCIF) video sequences scanned at 10 frames/s is offered. These codecs were designed to allow direct replacement of mobile radio voice codecs in second generation wireless systems, such as the Pan-European GSM, the American IS-54 ...

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 ...

A Novel H.264/AVC Based Multi-View Video Coding Scheme [PDF]
, 2008 This paper investigates extensions of H.264/AVC for compressing multi-view video sequences. The proposed technique re-sorts frames of sequences captured by multiple cameras looking at a person in a scene from different views and generates a single video ...
