A Novel Quantised Image Sensing for Machine Vision
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
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 ...

Content-Adaptive Packetization and Streaming of Wavelet Video over IP Networks
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 ...

Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images
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.

Linking individual variation in facial musculature to facial behavior in rhesus macaques
Abstract Facial expression is a key component of primate communication, and primates (including humans) have a complex system of facial musculature underpinning this behavior. Human facial musculature is highly variable across individuals, but to date, whether other primate species exhibit a similar level of inter‐individual variation is unknown ...
