Merged summary
TL;DR - A new framework (SSRL) tackles unsupervised visible-infrared person re-identification by turning noisy open-loop cross-modal association into a self-correcting closed-loop system, improving robustness without identity annotations.
- Problem: USVI-ReID struggles with a large modality gap and no cross-modal labels; prior progressive-association methods rely on ambiguous global features and propagate pseudo-label noise unchecked.
- Fine-grained Structural Decoupling (FSD): Extracts discriminative body-part primitives as reliable spatial anchors to complement ambiguous holistic silhouettes.
- Closed-loop Semantic Calibration (CSC): Rebuilds shared semantic prototypes each epoch and feeds them back to filter pseudo-label noise before the next clustering cycle.
- Results: Competitive with state-of-the-art USVI-ReID methods on SYSU-MM01 and RegDB, reportedly surpassing several supervised approaches on RegDB (no specific metrics given in the provided content).
