Ruian He | 何瑞安
I am a 3rd-year PhD student in School of Computer Science at Fudan University, supervised by Prof. Bo Yan. Before that, I received my Bachelor's degree of Computer Science at Fudan University in 2021. My research interests lie in the field of low-level vision, with application to rendering and microscopy imaging.

FacialFlowNet: Advancing Facial Optical Flow Estimation with a Diverse Dataset and a Decomposed Model
Jianzhi Lu*, Ruian He*, Shili Zhou, Weimin Tan, Bo Yan
ACMMM, 2024
We proposes FacialFlowNet, a novel large-scale facial optical flow dataset, and the Decomposed Facial Flow Model, the first method capable of decomposing facial flow.

Pre-training a Foundation Model for Generalizable Fluorescence Microscopy-Based Image Restoration
Chenxi Ma*, Weimin Tan*, Ruian He, Bo Yan
Nature Methods, 2024
We provide a universal fluorescence microscopy-based image restoration (UniFMIR) model to address different restoration problems, and show that UniFMIR offers higher image restoration precision, better generalization and increased versatility.

Low-latency Space-time Supersampling for Real-time Rendering
Ruian He*, Shili Zhou*, Yuqi Sun, Ri Cheng, Weimin Tan , Bo Yan
AAAI, 2024
We recognize the shared context and mechanisms between frame supersampling and extrapolation, save up to 75% of time against the conventional two-stage pipeline that necessitates 17ms.

SAMFlow: Eliminating Any Fragmentation in Optical Flow with Segment Anything Model
Shili Zhou, Ruian He, Weimin Tan , Bo Yan
AAAI, 2024
Through theoretical analysis, we find the pre-trained large vision models are helpful in optical flow estimation, and SAM is suitable for solving the fragmentation problem.

Context-Aware Iteration Policy Network for Efficient Optical Flow Estimation
Ri Cheng, Ruian He, Xuhao Jiang, Shili Zhou, Weimin Tan , Bo Yan
AAAI, 2024
We develop a Context-Aware Iteration Policy Network, which determines the optimal number of iterations per sample and reduce FLOPs by about 40%/20% for the Sintel/KITTI datasets.

Uncertainty-Guided Spatial Pruning Architecture for Efficient Frame Interpolation
Ri Cheng , Xuhao Jiang , Ruian He, Shili Zhou , Weimin Tan , Bo Yan
ACMMM, 2023
We develop an Uncertainty-Guided Spatial Pruning (UGSP) architecture to skip redundant computation for efficient frame interpolation dynamically.

MVFlow: Deep Optical Flow Estimation of Compressed Videos with Motion Vector Prior
Shili Zhou*, Xuhao Jiang*, Weimin Tan, Ruian He, Bo Yan
ACMMM, 2023
We propose an optical flow model, MVFlow, which uses motion vectors to improve the speed and accuracy of optical flow estimation for compressed videos.

Motion Matters: Difference-based Multi-scale Learning for Infrared UAV Detection
Ruian He, Shili Zhou, Ri Cheng, Yuqi Sun, Weimin Tan, Bo Yan
The 3nd Anti-UAV Workshop & Challenge - CVPR Workshops, 2023
Our method utilizes the frame difference of multiple previous frames and fuse multiple spatial-temporal scales.

Fine-grained Blind Face Inpainting with 3D Face Component Disentanglement
Yu Bai, Ruian He, Weimin Tan, Bo Yan, Yangle Lin
ICASSP, 2023
We propose a novel fine-grained blind face inpainting framework and build up a new dataset called CelebO-3D.

Co-completion for occluded facial expression recognition
Zhen Xing*, Weimin Tan*, Ruian He, Yangle Lin, Bo Yan
ACMMM, 2022
We propose a task-specific framework which first combines occlusion discarding and feature completion together to reduce the interference of occlusions on instance level.
