{"url":"/dataset/crowdflow","name":"CrowdFlow","full_name":"TUB CrowdFlow","description_markdown":"The **TUB CrowdFlow** is a synthetic dataset that contains 10 sequences showing 5 scenes. Each scene is rendered twice: with a static point of view and a dynamic camera to simulate drone/UAV based surveillance. The scenes are render using Unreal Engine at HD resolution (1280x720) at 25 fps, which is typical for current commercial CCTV surveillance systems. The total number of frames is 3200.\r\n\r\nEach sequence has the following ground-truth data:\r\n\r\n* Optical flow fields\r\n* Person trajectories (up to 1451)\r\n* Dense pixel trajectories\r\n\r\nSource: [Optical Flow Dataset and Benchmark for Visual Crowd Analysis](/paper/optical-flow-dataset-and-benchmark-for-visual)","description_withheld":null,"homepage":"https://github.com/tsenst/CrowdFlow","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/optical-flow-dataset-and-benchmark-for-visual","title":"Optical Flow Dataset and Benchmark for Visual Crowd Analysis","first_author":"Gregory Schröder","url":null},"license":null,"modalities":[{"name":"Videos","url":"/datasets/modality/videos"}],"tasks":[{"name":"Crowd Counting","url":"/task/crowd-counting","datasets_with_task":"/datasets/task/crowd-counting"},{"name":"Optical Flow Estimation","url":"/task/optical-flow-estimation","datasets_with_task":"/datasets/task/optical-flow-estimation"},{"name":"Visual Crowd Analysis","url":"/task/visual-crowd-analysis","datasets_with_task":"/datasets/task/visual-crowd-analysis"}],"languages":[],"variants":["CrowdFlow"],"data_loaders":[{"repo":"https://github.com/tsenst/CrowdFlow","url":"https://github.com/tsenst/CrowdFlow","frameworks":[]}],"num_papers_in_archive":4,"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":"2026-09-24T18:15:14+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."}
