DK-SLAM: Monocular Visual SLAM with Deep Keypoints Adaptive Learning, Tracking and Loop-Closing

no code implementations17 Jan 2024 Hao Qu, Lilian Zhang, Jun Mao, Junbo Tie, Xiaofeng He, Xiaoping Hu, Yifei Shi, Changhao Chen

Unreliable feature extraction and matching in handcrafted features undermine the performance of visual SLAM in complex real-world scenarios.

Continual Learning through Networks Splitting and Merging with Dreaming-Meta-Weighted Model Fusion

no code implementations12 Dec 2023 Yi Sun, Xin Xu, Jian Li, Guanglei Xie, Yifei Shi, Qiang Fang

Differently, we propose a continual learning method named Split2MetaFusion which can achieve better trade-off by employing a two-stage strategy: splitting and meta-weighted fusion.

SuperUDF: Self-supervised UDF Estimation for Surface Reconstruction

1 code implementation28 Aug 2023 Hui Tian, Chenyang Zhu, Yifei Shi, Kai Xu

The key insight is that if the UDF is estimated correctly, the 3D points should be locally projected onto the underlying surface following the gradient of the UDF.

Learning Task-preferred Inference Routes for Gradient De-conflict in Multi-output DNNs

no code implementations31 May 2023 Yi Sun, Xin Xu, Jian Li, Xiaochang Hu, Yifei Shi, Ling-Li Zeng

By designing the learnable task-specific importance variables, DR-MGF evaluates the importance of filters for different tasks.

SOCS: Semantically-aware Object Coordinate Space for Category-Level 6D Object Pose Estimation under Large Shape Variations

no code implementations ICCV 2023 Boyan Wan, Yifei Shi, Kai Xu

We propose Semantically-aware Object Coordinate Space (SOCS) built by warping-and-aligning the objects guided by a sparse set of keypoints with semantically meaningful correspondence.

Rescan: Inductive Instance Segmentation for Indoor RGBD Scans

no code implementations ICCV 2019 Maciej Halber, Yifei Shi, Kai Xu, Thomas Funkhouser

In depth-sensing applications ranging from home robotics to AR/VR, it will be common to acquire 3D scans of interior spaces repeatedly at sparse time intervals (e. g., as part of regular daily use).

Recurrent 3D Attentional Networks for End-to-End Active Object Recognition

no code implementations14 Oct 2016 Min Liu, Yifei Shi, Lintao Zheng, Kai Xu, Hui Huang, Dinesh Manocha

Active vision is inherently attention-driven: The agent actively selects views to attend in order to fast achieve the vision task while improving its internal representation of the scene being observed.
