ANMS: Asynchronous Non-Maximum Suppression in Event Stream

1 code implementation19 Mar 2023 Qianang Zhou, Junlin Xiong, Youfu Li

As a result, the performance of event-based corner detectors is limited.

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.

A Temporal Densely Connected Recurrent Network for Event-based Human Pose Estimation

1 code implementation15 Sep 2022 Zhanpeng Shao, Wen Zhou, Wuzhen Wang, Jianyu Yang, Youfu Li

By this recurrent architecture, we can explicitly model not only the sequential but also non-sequential geometric consistency across time steps to accumulate information from previous frames to recover the entire human bodies, achieving a stable and accurate human pose estimation from event data.

A Voxel Graph CNN for Object Classification with Event Cameras

no code implementations CVPR 2022 Yongjian Deng, Hao Chen, Hai Liu, Youfu Li

This study aims to address the core problem of balancing accuracy and model complexity for event-based classification models.

CNN-based RGB-D Salient Object Detection: Learn, Select and Fuse

no code implementations20 Sep 2019 Hao Chen, Youfu Li

The goal of this work is to present a systematic solution for RGB-D salient object detection, which addresses the following three aspects with a unified framework: modal-specific representation learning, complementary cue selection and cross-modal complement fusion.

BigData Applications from Graph Analytics to Machine Learning by Aggregates in Recursion

no code implementations18 Sep 2019 Ariyam Das, Youfu Li, Jin Wang, Mingda Li, Carlo Zaniolo

In the past, the semantic issues raised by the non-monotonic nature of aggregates often prevented their use in the recursive statements of logic programs and deductive databases.

Progressively Complementarity-Aware Fusion Network for RGB-D Salient Object Detection

1 code implementation CVPR 2018 Hao Chen, Youfu Li

In this paper, we answer this question from two perspectives: (1) We argue that if the complementary part can be modelled more explicitly, the cross-modal complement is likely to be better captured.

RRV: A Spatiotemporal Descriptor for Rigid Body Motion Recognition

no code implementations18 Jun 2016 Yao Guo, Youfu Li, Zhanpeng Shao

Motion behaviors of a rigid body can be characterized by a 6-dimensional motion trajectory, which contains position vectors of a reference point on the rigid body and rotations of this rigid body over time.
