The dataset can be divided into two subsets: one cloth-change set where 91 persons appear with 416 different sets of outfits in 14,783 images, and one cloth-consistent subset containing the remaining 61 identities with 2,336 images without outfit changes. On average, there are 5 different clothes for each cloth-changing person, with the number of outfit changes ranging from 2 to 14.\r\n\r\nSource: [LTCC dataset homepage](https://naiq.github.io/LTCC_Perosn_ReID.html)","description_withheld":null,"homepage":"https://naiq.github.io/LTCC_Perosn_ReID.html","introduced_date":"2020-05-26","introduced_date_note":null,"introduced_by":{"paper":"/paper/long-term-cloth-changing-person-re","title":"Long-Term Cloth-Changing Person Re-identification","first_author":"Xuelin Qian","url":null},"license":null,"modalities":[],"tasks":[{"name":"Person Re-Identification","url":"/task/person-re-identification","datasets_with_task":"/datasets/task/person-re-identification"},{"name":"Unsupervised Person Re-Identification","url":"/task/unsupervised-person-re-identification","datasets_with_task":"/datasets/task/unsupervised-person-re-identification"}],"languages":[],"variants":["LTCC"],"data_loaders":[],"num_papers_in_archive":38,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/person-re-identification-on-ltcc","task":"Person Re-Identification","dataset_variant":"LTCC","rows":13,"metrics":[" Rank-1"," mAP","mAP","Rank-1"],"first_row_in_archive_order":{"model":"CSCI","paper":"/paper/colors-see-colors-ignore-clothes-changing","metrics":{" Rank-1":"50.3"," mAP":"25.9"},"code_links":[]},"note":"rows are the archive's own order at snapshot;
