CIA: Cluster-Instance Alignment for Unsupervised Day-Night Vehicle Re-Identification

AAAI 2026technical

Cross-time vehicle re-identification (Re-ID), especially across day and night conditions, remains a challenging problem due to drastic illumination variations that lead to significant domain shifts. While existing methods perform well under daytime scenarios, their effectiveness degrades severely in

Cross-Modality Earth Mover’s Distance for Visible Thermal Person Re-identification

AAAI 2023technical

Visible thermal person re-identification (VT-ReID) suffers from inter-modality discrepancy and intra-identity variations. Distribution alignment is a popular solution for VT-ReID, however, it is usually restricted to the influence of the intra-identity variations. In this paper, we propose the Cross…

A Multi-Constraint Similarity Learning with Adaptive Weighting for Visible-Thermal Person Re-Identification

IJCAI 2021poster

The challenges of visible-thermal person re-identification (VT-ReID) lies in the inter-modality discrepancy and the intra-modality variations. An appropriate metric learning plays a crucial role in optimizing the feature similarity between the two modalities. However, most existing metric learning-…
