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 ...

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 ...

Video Codecs Simulation and Compare QoS Characteristics of Different Video Codecs
Education and Research Archive, 2014 In this project QoS characteristics of different video codecs are compared. QoS characteristics of H.265 and H.264 video codecs are tested and compared on identical network conditions and load. Traffic is running on a subset sample of Telus network. To carry out the simulation OMNET++ is used, OMNET++ is a network simulating software.

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 ...
