View-decoupled Transformer for Person Re-identification in Aerial-ground Camera Network
Core Concepts
Proposing the View-decoupled Transformer (VDT) for effective person re-identification in aerial-ground camera networks by decoupling view-related and view-unrelated features.
Abstract
Introduction
Existing methods focus on homogeneous cameras, while aerial-ground matching is neglected.
VDT aims to address the challenge of dramatic view discrepancy in AGPReID.
Method
VDT framework involves hierarchical subtractive separation and orthogonal loss for feature decoupling.
Dataset: CARGO
Large-scale dataset with 5,000 identities and 108,563 images simulating real-world scenarios.
Experiment
VDT outperforms baseline methods on CARGO and AG-ReID datasets.
Ablation Study
Demonstrates the importance of both hierarchical subtractive separation and orthogonal loss in VDT performance.
Parameter Analysis
Optimal performance achieved at specific values of hyperparameter λ on different datasets.
Conclusion and Future Work
VDT offers a state-of-the-art solution for AGPReID, highlighting the need for further research on identity representation under various disturbances.
