Relative Distance Guided Dynamic Partition Learning for Scale-Invariant UAV-View Geo-Localization

no code implementations16 Dec 2024 Quan Chen, Tingyu Wang, Rongfeng Lu, Bolun Zheng, Zhedong Zheng, Chenggang Yan

Specifically, we propose a distance guided dynamic partition learning strategy~(DGDPL), consisting of a square partition strategy and a distance-guided adjustment strategy.

The Impact of Scanner Domain Shift on Deep Learning Performance in Medical Imaging: an Experimental Study

no code implementations6 Sep 2024 Brian Guo, Darui Lu, Gregory Szumel, Rongze Gui, Tingyu Wang, Nicholas Konz, Maciej A. Mazurowski

This phenomenon, scanner domain shift, can result in a drop in the performance of deep neural networks which are trained on data acquired by one scanner and tested on another.

SDPL: Shifting-Dense Partition Learning for UAV-View Geo-Localization

1 code implementation7 Mar 2024 Quan Chen, Tingyu Wang, Zihao Yang, Haoran Li, Rongfeng Lu, Yaoqi Sun, Bolun Zheng, Chenggang Yan

We propose a dense partition strategy (DPS), dividing the image into multiple parts to explore contextual information while explicitly maintaining the global structure.

Towards Natural Language-Guided Drones: GeoText-1652 Benchmark with Spatial Relation Matching

2 code implementations21 Nov 2023 Meng Chu, Zhedong Zheng, Wei Ji, Tingyu Wang, Tat-Seng Chua

Navigating drones through natural language commands remains challenging due to the dearth of accessible multi-modal datasets and the stringent precision requirements for aligning visual and textual data.

Learning Cross-view Geo-localization Embeddings via Dynamic Weighted Decorrelation Regularization

no code implementations10 Nov 2022 Tingyu Wang, Zhedong Zheng, Zunjie Zhu, Yuhan Gao, Yi Yang, Chenggang Yan

Cross-view geo-localization aims to spot images of the same location shot from two platforms, e. g., the drone platform and the satellite platform.

Each Part Matters: Local Patterns Facilitate Cross-view Geo-localization

1 code implementation26 Aug 2020 Tingyu Wang, Zhedong Zheng, Chenggang Yan, Jiyong Zhang, Yaoqi Sun, Bolun Zheng, Yi Yang

Existing methods usually concentrate on mining the fine-grained feature of the geographic target in the image center, but underestimate the contextual information in neighbor areas.

Inexact Krylov iterations and relaxation strategies with fast-multipole boundary element method

2 code implementations19 Jun 2015 Tingyu Wang, Simon K. Layton, Lorena A. Barba

We take advantage of a unique property of Krylov iterations that allow lower accuracy of the matrix-vector products as convergence proceeds, and propose a relaxation strategy based on progressively decreasing $p$.
