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 ...

Variational Bayesian Inference Deraining Network Based on Latent Variable Grouping

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes a variational Bayesian inference deraining network that integrates model‐driven and data‐driven approaches within a unified framework. By introducing a latent variable grouping strategy and a residual distribution mechanism, the network effectively models complex rain streak distributions while ensuring training stability. Extensive

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.
