| 英文摘要 | Person Re-Identifification (Re-ID) has witnessed great im
provements due to the advances of the deep convolutional
neural networks (CNN). Despite this, existing methods
mainly suffer from the poor generalization ability to unseen
persons because of the different characteristics between dif
ferent domains. To address this issue, a Clustering and Dy
namic Sampling (CDS) method is proposed in this paper,
which tries to transfer the useful knowledge of existing la
beled source domain to the unlabeled target one. Specififically,
to improve the discriminability of CNN model on source do
main, we use the commonly shared pedestrian attributes (e.g.,
gender, hat and clothing color etc.) to enrich the informa
tion and resort to the margin-based softmax (e.g., A-Softmax)
loss to train the model. For the unlabeled target domain, we
iteratively cluster the samples into several centers and dy
namically select informative ones from each center to fifine
tune the source-domain model. Extensive experiments on the
DukeMTMC-reID-reID and Market-1501 datasets show that
the proposed method largely improves the state of the arts in
unsupervised domain adaptation. |
