{"url":"/dataset/vcsl","name":"VCSL","full_name":"Video Copy Segment Localization","description_markdown":"VCSL (Video Copy Segment Localization) is a new comprehensive segment-level annotated video copy dataset. Compared with existing copy detection datasets restricted by either video-level annotation or small-scale, VCSL not only has two orders of magnitude more segment level labelled data, with 160k realistic video copy pairs containing more than 280k localized copied segment pairs, but also covers a variety of video categories and a wide range of video duration. All the copied segments inside each collected video pair are manually extracted and accompanied by precisely annotated starting and ending timestamps.","description_withheld":null,"homepage":"https://github.com/alipay/VCSL","introduced_date":"2022-03-05","introduced_date_note":null,"introduced_by":{"paper":"/paper/a-large-scale-comprehensive-dataset-and-copy","title":"A Large-scale Comprehensive Dataset and Copy-overlap Aware Evaluation Protocol for Segment-level Video Copy Detection","first_author":"Sifeng He","url":null},"license":{"name":"MIT","url":"https://github.com/alipay/VCSL/blob/main/LICENSE"},"modalities":[{"name":"Videos","url":"/datasets/modality/videos"}],"tasks":[{"name":"Copy Detection","url":"/task/copy-detection","datasets_with_task":"/datasets/task/copy-detection"}],"languages":[],"variants":["VCSL"],"data_loaders":[],"num_papers_in_archive":5,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
