FMRT: Learning Accurate Feature Matching with Reconciliatory Transformer

no code implementations20 Oct 2023 Xinyu Zhang, Li Wang, Zhiqiang Jiang, Kun Dai, Tao Xie, Lei Yang, Wenhao Yu, Yang shen, Jun Li

However, these methods only integrate long-range context information among keypoints with a fixed receptive field, which constrains the network from reconciling the importance of features with different receptive fields to realize complete image perception, hence limiting the matching accuracy.

OFVL-MS: Once for Visual Localization across Multiple Indoor Scenes

1 code implementation ICCV 2023 Tao Xie, Kun Dai, Siyi Lu, Ke Wang, Zhiqiang Jiang, Jinghan Gao, Dedong Liu, Jie Xu, Lijun Zhao, Ruifeng Li

In this work, we seek to predict camera poses across scenes with a multi-task learning manner, where we view the localization of each scene as a new task.

DeepMatcher: A Deep Transformer-based Network for Robust and Accurate Local Feature Matching

1 code implementation8 Jan 2023 Tao Xie, Kun Dai, Ke Wang, Ruifeng Li, Lijun Zhao

In this work, we propose DeepMatcher, a deep Transformer-based network built upon our investigation of local feature matching in detector-free methods.

Poly-PC: A Polyhedral Network for Multiple Point Cloud Tasks at Once

no code implementations CVPR 2023 Tao Xie, Shiguang Wang, Ke Wang, Linqi Yang, Zhiqiang Jiang, Xingcheng Zhang, Kun Dai, Ruifeng Li, Jian Cheng

In this work, we show that it is feasible to perform multiple tasks concurrently on point cloud with a straightforward yet effective multi-task network.

CO-Net: Learning Multiple Point Cloud Tasks at Once with A Cohesive Network

no code implementations ICCV 2023 Tao Xie, Ke Wang, Siyi Lu, Yukun Zhang, Kun Dai, Xiaoyu Li, Jie Xu, Li Wang, Lijun Zhao, Xinyu Zhang, Ruifeng Li

Finally, we propose a sign-based gradient surgery to promote the training of CO-Net, thereby emphasizing the usage of task-shared parameters and guaranteeing that each task can be thoroughly optimized.
