Unsupervised Cross-Domain Person Re-Identification Method Based on Attention Block and Refined Clustering

open access: yesIEEE Access, 2022
Most unsupervised cross-domain person re-identification methods based on clustering suffer from a lack of feature discrimination and clustering generates pseudo-labels noise, leading to a decrease in accuracy. To solve these problems, this paper proposes

Sonification of Network Traffic Flow for Monitoring and Situational Awareness [PDF]

open access: yes, 2017
Maintaining situational awareness of what is happening within a network is challenging, not least because the behaviour happens within computers and communications networks, but also because data traffic speeds and volumes are beyond human ability to ...

An Improved Splicing Localization Method by Fully Convolutional Networks

open access: yesIEEE Access, 2018
Liu and Pun proposed a method based on fully convolutional network (FCN) and conditional random field (CRF) to locate spliced regions in synthesized images from different source images. However, their work has two drawbacks: 1) FCN often smooths detailed
