Event-based Video Frame Interpolation with Edge Guided Motion Refinement

no code implementations28 Apr 2024 YuHan Liu, Yongjian Deng, Hao Chen, Bochen Xie, Youfu Li, Zhen Yang

Moreover, given that event data can provide accurate visual references at scene edges between consecutive frames, we introduce a learned visibility map derived from event data to adaptively mitigate the occlusion problem in the warping refinement process.

Data-efficient Event Camera Pre-training via Disentangled Masked Modeling

no code implementations1 Mar 2024 Zhenpeng Huang, Chao Li, Hao Chen, Yongjian Deng, Yifeng Geng, LiMin Wang

Our pre-training overcomes the limitations of previous methods, which either sacrifice temporal information by converting event sequences into 2D images for utilizing pre-trained image models or directly employ paired image data for knowledge distillation to enhance the learning of event streams.

Interpretation on Multi-modal Visual Fusion

no code implementations19 Aug 2023 Hao Chen, Haoran Zhou, Yongjian Deng

In this paper, we present an analytical framework and a novel metric to shed light on the interpretation of the multimodal vision community.

Event Voxel Set Transformer for Spatiotemporal Representation Learning on Event Streams

no code implementations7 Mar 2023 Bochen Xie, Yongjian Deng, Zhanpeng Shao, Hai Liu, Qingsong Xu, Youfu Li

To fit the sparse nature of events and sufficiently explore the relationship between them, we develop a novel attention-aware model named Event Voxel Set Transformer (EVSTr) for spatiotemporal representation learning on event streams.

TokenHPE: Learning Orientation Tokens for Efficient Head Pose Estimation via Transformers

1 code implementation CVPR 2023 Cheng Zhang, Hai Liu, Yongjian Deng, Bochen Xie, Youfu Li

To leverage the observed findings, we propose a novel critical minority relationship-aware method based on the Transformer architecture in which the facial part relationships can be learned.

TransIFC: Invariant Cues-aware Feature Concentration Learning for Efficient Fine-grained Bird Image Classification

no code implementations TIP 2022 Hai Liu, Cheng Zhang, Yongjian Deng, Bochen Xie, Tingting Liu, Zhaoli Zhang, You-Fu Li

To this end, two novel modules are proposed to leverage the characteristics of bird images, namely, the hierarchy stage feature aggregation (HSFA) module and the feature in feature abstraction (FFA) module.
