{"url":"/dataset/atlantis","name":"ATLANTIS","full_name":null,"description_markdown":"**ATLANTIS** is a benchmark for semantic segmentation of waterbody images. This dataset covers a wide range of natural waterbodies such as sea, lake, river and man-made (artificial) water-related structures such as dam, reservoir, canal, and pier. ATLANTIS includes 5,195 pixel-wise annotated images split to 3,364 training, 535 validation, and 1,296 testing images. In addition to 35 waterbodies, this dataset covers 21 general labels such as person, car, road and building.","description_withheld":null,"homepage":"https://github.com/smhassanerfani/atlantis","introduced_date":"2021-11-22","introduced_date_note":null,"introduced_by":{"paper":"/paper/atlantis-a-benchmark-for-semantic","title":"ATLANTIS: A Benchmark for Semantic Segmentation of Waterbody Images","first_author":"Seyed Mohammad Hassan Erfani","url":null},"license":{"name":"Unknown","url":null},"modalities":[],"tasks":[{"name":"Semantic Segmentation","url":"/task/semantic-segmentation","datasets_with_task":"/datasets/task/semantic-segmentation"},{"name":"Reinforcement Learning","url":"/task/reinforcement-learning","datasets_with_task":"/datasets/task/reinforcement-learning"}],"languages":[],"variants":["ATLANTIS"],"data_loaders":[],"num_papers_in_archive":2,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/semantic-segmentation-on-atlantis","task":"Semantic Segmentation","dataset_variant":"ATLANTIS","rows":1,"metrics":["A-acc","A-mIoU","Accuracy","mIoU"],"first_row_in_archive_order":{"model":"Erfani et al.","paper":"/paper/atlantis-a-benchmark-for-semantic","metrics":{"A-acc":"68.63","A-mIoU":"50.34","Accuracy":"75.18","mIoU":"42.22"},"code_links":[{"title":"smhassanerfani/atlantis","url":"https://github.com/smhassanerfani/atlantis"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/atlantis-a-benchmark-for-semantic","title":"ATLANTIS: A Benchmark for Semantic Segmentation of Waterbody Images","date":"2021-11-22","rows_on_this_dataset":1,"code_links":1,"syntology":null}],"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."}
