JSTR: Joint Spatio-Temporal Reasoning for Event-based Moving Object Detection

no code implementations12 Mar 2024 Hanyu Zhou, Zhiwei Shi, Hao Dong, Shihan Peng, Yi Chang, Luxin Yan

In spatial reasoning stage, we project the compensated events into the same image coordinate, discretize the timestamp of events to obtain a time image that can reflect the motion confidence, and further segment the moving object through adaptive threshold on the time image.

Bring Event into RGB and LiDAR: Hierarchical Visual-Motion Fusion for Scene Flow

no code implementations12 Mar 2024 Hanyu Zhou, Yi Chang, Zhiwei Shi, Luxin Yan

In this work, we bring the event as a bridge between RGB and LiDAR, and propose a novel hierarchical visual-motion fusion framework for scene flow, which explores a homogeneous space to fuse the cross-modal complementary knowledge for physical interpretation.

Exploring the Common Appearance-Boundary Adaptation for Nighttime Optical Flow

no code implementations31 Jan 2024 Hanyu Zhou, Yi Chang, Haoyue Liu, Wending Yan, Yuxing Duan, Zhiwei Shi, Luxin Yan

In appearance adaptation, we employ the intrinsic image decomposition to embed the auxiliary daytime image and the nighttime image into a reflectance-aligned common space.
