TL;DR: Spatial Decomposition Network (SDNet) is proposed, which factorises 2D medical images into spatial anatomical factors and non-spatial modality factors and is ideally suited for several medical image analysis tasks, such as semi-supervised segmentation, multi-task segmentation and regression, and image-to-image synthesis.
Journal ArticleDOI
SaliencyGAN: Deep Learning Semisupervised Salient Object Detection in the Fog of IoT
TL;DR: This article introduces a semisupervised adversarial learning method, named as SaliencyGAN, empowered by a novel concatenated generative adversarial network (GAN) framework with partially shared parameters to adopt convolutional neural networks on fog–cloud infrastructures for SOD-based applications.
Journal ArticleDOI

TL;DR: It is shown that BMAT glucose uptake is not insulin or cold responsive; however, BMAT basal glucose uptake are higher than in white adipose tissue or skeletal muscle, underscoring BMAT’s potential to influence systemic glucose homeostasis.
Journal ArticleDOI
DiCyc: GAN-based deformation invariant cross-domain information fusion for medical image synthesis.
Chengjia Wang,Guang Yang,Giorgos Papanastasiou,Sotirios A. Tsaftaris,David E. Newby,Calum Gray,Gillian Macnaught,Tom MacGillivray +7 more
TL;DR: A deformation invariant cycle-consistency model is presented that can achieve better alignment between the source and target data while maintaining superior image quality of signal compared to several state-of-the-art CycleGAN-based methods.
Journal ArticleDOI
Peripheral Retinal Imaging Biomarkers for Alzheimer's Disease: A Pilot Study.

TL;DR: UWF retinal imaging revealed a significant association between AD and peripheral hard drusen formation and changes to the vasculature beyond the posterior pole, at BL and after clinical progression over 2 years, suggesting that monitoring pathological changes in the peripheral retina might become a valuable tool in AD monitoring.
