Global feature\nlearning benefits greatly from local feature learning, which performs an\nalignment/matching by calculating the shortest path between two sets of local\nfeatures, without requiring extra supervision. After the joint learning, we\nonly keep the global feature to compute the similarities between images. Our\nmethod achieves rank-1 accuracy of 94.4% on Market1501 and 97.8% on CUHK03,\noutperforming state-of-the-art methods by a large margin. We also evaluate\nhuman-level performance and demonstrate that our method is the first to surpass\nhuman-level performance on Market1501 and CUHK03, two widely used Person ReID\ndatasets.","url_abs":"http://arxiv.org/abs/1711.08184v2","url_pdf":"http://arxiv.org/pdf/1711.08184v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA
