- Abstract summary: We propose a Hard Samples Rectification learning scheme which resolves the weakness of original clustering-based methods.
Our HSR contains two parts, an inter-camera mining method that helps recognize a person under different views (hard positive) and a part-based homogeneity technique that makes the model discriminate different persons but with similar appearance (hard negative)
By rectifying those two hard cases, the re-ID model can learn effectively and achieve promising results on two large-scale benchmarks.

- Abstract: Person re-identification (re-ID) has received great success with the
supervised learning methods. However, the task of unsupervised cross-domain
re-ID is still challenging. In this paper, we propose a Hard Samples
Rectification (HSR) learning scheme which resolves the weakness of original
clustering-based methods being vulnerable to the hard positive and negative
samples in the target unlabelled dataset. Our HSR contains two parts, an
inter-camera mining method that helps recognize a person under different views
(hard positive) and a part-based homogeneity technique that makes the model
discriminate different persons but with similar appearance (hard negative). By
rectifying those two hard cases, the re-ID model can learn effectively and
achieve promising results on two large-scale benchmarks.

We proposed a novel self-supervision and supervision combining transformer-based person re-identification framework, namely SSSC-TransReID.
We designed a self-supervised contrastive learning branch, which can enhance the feature representation for person re-identification without negative samples or additional pre-training.
Our proposed model obtains superior Re-ID performance consistently and outperforms the state-of-the-art ReID methods by large margins on the mean average accuracy (mAP) and Rank-1 accuracy.

Our proposed method achieves state-of-the-art in several challenging benchmarks, and improves upon existing SSL methods even when ID samples are totally absent in unlabeled data.

Clustering sometimes mixes different true identities together or splits the same identity into two or more sub clusters.
We propose an Implicit Sample Extension (OurWholeMethod) method to generate what we call support samples around the cluster boundaries.
Experiments demonstrate that the proposed method is effective and achieves state-of-the-art performance for unsupervised person Re-ID.

We present a novel selective tracklet learning (STL) approach that can train discriminative person re-id models from unlabelled tracklet data.
This avoids the tedious and costly process of exhaustively labelling person image/tracklet true matching pairs across camera views.
Our method is particularly more robust against arbitrary noisy data of raw tracklets therefore scalable to learning discriminative models from unconstrained tracking data.
