AnF-DiffPET: Anatomy- and Frequency-Guided Diffusion for PET/CT Denoising
Xuepeng Liu, Ruili Li, Zetong Liu +5
Positron emission tomography (PET) provides essential functional information for disease assessment, however reducing injected activity or acquisition time produces low-dose (LD) P…
FOD-Diff: 3D Multi-Channel Patch Diffusion Model for Fiber Orientation Distribution
Hao Tang, Hanyu Liu, Alessandro Perelli +2
Diffusion MRI (dMRI) is a critical non-invasive technique to estimate fiber orientation distribution (FOD) for characterizing white matter integrity. Estimating FOD from single-she…
Confidence-driven Gradient Modulation for Multimodal Human Activity Recognition: A Dynamic Contrastive Dual-Path Learning Approach
Panpan Ji, Junni Song, Yifan Lu +3
Sensor-based Human Activity Recognition (HAR) is a core technology that enables intelligent systems to perceive and interact with their environment. However, multimodal HAR systems…
HaDM-ST: Histology-Assisted Differential Modeling for Spatial Transcriptomics Generation
Xuepeng Liu, Zheng Jiang, Pinan Zhu +2
Spatial transcriptomics (ST) reveals spatial heterogeneity of gene expression, yet its resolution is limited by current platforms. Recent methods enhance resolution via H&E-stained…
USAD: End-to-End Human Activity Recognition via Diffusion Model with Spatiotemporal Attention
Hang Xiao, Ying Yu, Jiarui Li +4
The primary objective of human activity recognition (HAR) is to infer ongoing human actions from sensor data, a task that finds broad applications in health monitoring, safety prot…
