{"url":"/dataset/messytable","name":"MessyTable","full_name":"MessyTable","description_markdown":"**MessyTable** features a large number of scenes with messy tables captured from multiple camera views. Each scene in this dataset is highly complex, containing multiple object instances that could be identical, stacked and occluded by other instances. The key challenge is to associate all instances given the RGB image of all views. The seemingly simple task surprisingly fails many popular methods or heuristics. The dataset challenges existing methods in mining subtle appearance differences, reasoning based on contexts, and fusing appearance with geometric cues for establishing an association.\r\n\r\nThere are 50,211 images and 5,579 scenes in the dataset.","description_withheld":null,"homepage":"https://caizhongang.github.io/projects/MessyTable/","introduced_date":"2020-07-29","introduced_date_note":null,"introduced_by":{"paper":"/paper/messytable-instance-association-in-multiple","title":"MessyTable: Instance Association in Multiple Camera Views","first_author":"Zhongang Cai","url":null},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[],"languages":[],"variants":["MessyTable"],"data_loaders":[],"num_papers_in_archive":1,"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."}
