x^2-Fusion: Cross-Modality and Cross-Dimension Flow Estimation in Event Edge Space

Ruishan Guo, Ciyu Ruan, Haoyang Wang, Zihang Gong, Jingao Xu, Xinlei Chen

CVPR 2026

Estimating dense 2D optical flow and 3D scene flow is essential for dynamic scene understanding. Recent work combines images, LiDAR, and event data to jointly predict 2D and 3D motion, yet most approaches operate in separate heterogeneous feature spaces. Without a shared latent space that all modali

PRE-Mamba: A 4D State Space Model for Ultra-High-Frequent Event Camera Deraining

Ciyu Ruan, Ruishan Guo, Zihang Gong, Jingao Xu, Wenhan Yang, Xinlei Chen

ICCV 2025poster

Event cameras excel in high temporal resolution and dynamic range but suffer from dense noise in rainy conditions. Existing event deraining methods face trade-offs between temporal precision, deraining effectiveness, and computational efficiency. In this paper, we propose PRE-Mamba, a novel point-ba…
