Phase-Aligned Finite-Fourier Periodic Deformation for 4D Medical Image Interpolation
Haojin Li, Hengzhuo Wang, Zhiheng Ma +3
4D medical image interpolation aims to recover missing volumes from sparsely observed time points and is important for dynamic anatomical analysis in applications such as cardiac M…
Low-Rank Velocity Fields as a Structural Prior for Unsupervised 4D Medical Image Interpolation
Haojin Li, Hengzhuo Wang, Chang Liu +3
Endpoint-only unsupervised 4D medical image interpolation synthesizes intermediate volumes from sparsely sampled sequences with only the start and end volumes available for trainin…
Adversarial Patch Generation for Visual-Infrared Dense Prediction Tasks via Joint Position-Color Optimization
He Li, Wenyue He, Weihang Kong +1
Multimodal adversarial attacks for dense prediction remain largely underexplored. In particular, visual-infrared (VI) perception systems introduce unique challenges due to heteroge…
RaffeSDG: Random Frequency Filtering enabled Single-source Domain Generalization for Medical Image Segmentation
Heng Li, Haojin Li, Jianyu Chen +3
Deep learning models often encounter challenges in making accurate inferences when there are domain shifts between the source and target data. This issue is particularly pronounced…
ACT-Net: Anchor-context Action Detection in Surgery Videos
Luoying Hao, Yan Hu, Wenjun Lin +5
Recognition and localization of surgical detailed actions is an essential component of developing a context-aware decision support system. However, most existing detection algorith…
