TRCoRSurg: Temporal-Relational Co-Reasoning for Surgical Video Triplet Recognition
Fang Li, Shihao Zou, Weixin Si +3
Understanding complex surgical scenes requires recognizing multiple interdependent entities, such as instruments, actions, and targets, while maintaining their relational consisten…
VoxStruct3D: Structure-Leading Flow Matching for Voxel-Space 3D MRI Synthesis
Fang Li, Yang Gao, Shihao Zou +5
High-fidelity 3D MRI synthesis requires both globally coherent anatomy and fine-grained voxel-level detail. Although latent diffusion makes volumetric generation tractable, its ima…
Towards Unified Surgical Scene Understanding:Bridging Reasoning and Grounding via MLLMs
Jincai Huang, Shihao Zou, Yuchen Guo +5
Surgical scene understanding is a cornerstone of computer-assisted intervention. While recent advances, particularly in surgical image segmentation, have driven progress, real-worl…
Toward Real-Time Surgical Scene Segmentation via a Spike-Driven Video Transformer with Spike-Informed Pretraining
Shihao Zou, Jingjing Li, Wei Ji +5
Modern surgical systems increasingly rely on intelligent scene understanding to improve intra-operative safety and situational awareness, with surgical scene segmentation playing a…
TempDiffReg: Temporal Diffusion Model for Non-Rigid 2D-3D Vascular Registration
Zehua Liu, Shihao Zou, Jincai Huang +3
Transarterial chemoembolization (TACE) is a preferred treatment option for hepatocellular carcinoma and other liver malignancies, yet it remains a highly challenging procedure due…
Multi-Modal Motion Retrieval by Learning a Fine-Grained Joint Embedding Space
Shiyao Yu, Zi-An Wang, Kangning Yin +4
Motion retrieval is crucial for motion acquisition, offering superior precision, realism, controllability, and editability compared to motion generation. Existing approaches levera…
