Content-Adaptive Packetization and Streaming of Wavelet Video over IP Networks
EURASIP Journal on Image and Video Processing, 2007 This paper presents a framework of content-adaptive packetization scheme for streaming of 3D wavelet-based video content over lossy IP networks. The tradeoff between rate and distortion is controlled by jointly adapting scalable source coding rate and ...

Two-Dimensional Iterative Source-Channel Decoding for Distributed Video Coding [PDF]
, 2014 Motivated by the Joint Source-Channel Decoding (JSCD) principle of exploiting the source redundancy, in this treatise we study the application of iterative source-channel decoding (ISCD) conceived for distributed video coding (DVC), where the video ...

A Novel Quantised Image Sensing for Machine Vision
Electronics Letters, Volume 62, Issue 1, January/December 2026.This paper shows that the image information quantised in the range of 1 to 4 bits can be utilised for object detection and tracking without any performance degradation. Thus, it is expected that the proposed technique holds promise for use in machine vision, not only maintaining the accuracy of detection and tracking, but even enabling more optimised ...

Comparative Insights: Fuzzy Clustering Versus Archetypal Analysis in Vector Quantisation for Blosc2
Electronics Letters, Volume 62, Issue 1, January/December 2026.Blosc2 is a high‐performance compression library for binary data like numerical arrays and tensors. This proposal aims to develop two new codecs, based on Archetypal Analysis (AA) and Fuzzy Clustering, using Blosc2's plugin‐based framework. Experiments on the Olivetti Faces dataset show that AA outperforms Fuzzy Clustering by better preserving fine ...

Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images
IET Signal Processing, Volume 2026, Issue 1, 2026.Underwater images serve as one of the most intuitive media for human perception of underwater environments. However, the limited bandwidth and susceptibility to noise in underwater acoustic (UWA) channels pose significant challenges for traditional image encoding and transmission methods, thereby hindering high‐quality image reconstruction.

A Key Embedded Video Codec for Secure Video Multicast [PDF]
, 2005 The problem of controlling access to multimedia multicasts requires the distribution and maintenance of keying information. This paper proposes a new key embedded video codec for the media-dependent approach that involves the use of a data-dependent channel, and can be achieved for multimedia by using data embedding techniques.

International Journal of Digital Multimedia Broadcasting, Volume 2026, Issue 1, 2026.The heterogeneity of the network at the edge creates unequal bandwidth availability for clients connected through diverse networks and devices. This variability can lead to bandwidth fluctuations and slow response times, resulting in buffering or degraded streaming performance.
