{"url":"/dataset/widerperson","name":"WiderPerson","full_name":null,"description_markdown":"WiderPerson contains a total of 13,382 images with 399,786 annotations, i.e., 29.87 annotations per image, which means this dataset contains dense pedestrians with various kinds of occlusions. Hence, pedestrians in the proposed dataset are extremely challenging due to large variations in the scenario and occlusion, which is suitable to evaluate pedestrian detectors in the wild.\r\n\r\nSource: [WiderPerson: A Diverse Dataset for Dense Pedestrian Detection in the Wild](/paper/widerperson-a-diverse-dataset-for-dense)\r\nImage Source: [http://www.cbsr.ia.ac.cn/users/sfzhang/WiderPerson/](http://www.cbsr.ia.ac.cn/users/sfzhang/WiderPerson/)","description_withheld":null,"homepage":"http://www.cbsr.ia.ac.cn/users/sfzhang/WiderPerson/","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/widerperson-a-diverse-dataset-for-dense","title":"WiderPerson: A Diverse Dataset for Dense Pedestrian Detection in the Wild","first_author":"Shifeng Zhang","url":null},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Object Detection","url":"/task/object-detection","datasets_with_task":"/datasets/task/object-detection"}],"languages":[],"variants":["WiderPerson"],"data_loaders":[],"num_papers_in_archive":11,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/object-detection-on-widerperson","task":"Object Detection","dataset_variant":"WiderPerson","rows":4,"metrics":["AP","mMR"],"first_row_in_archive_order":{"model":"IterDet (Faster RCNN, ResNet50, 2 iterations)","paper":"/paper/iterdet-iterative-scheme-for-objectdetection","metrics":{"AP":"91.95","mMR":"40.78"},"code_links":[]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/iterdet-iterative-scheme-for-objectdetection","title":"IterDet: Iterative Scheme for Object Detection in Crowded Environments","date":"2020-05-12","rows_on_this_dataset":2,"code_links":0,"syntology":null},{"paper":"/paper/ps-rcnn-detecting-secondary-human-instances","title":"PS-RCNN: Detecting Secondary Human Instances in a Crowd via Primary Object Suppression","date":"2020-03-16","rows_on_this_dataset":1,"code_links":0,"syntology":null},{"paper":"/paper/widerperson-a-diverse-dataset-for-dense","title":"WiderPerson: A Diverse Dataset for Dense Pedestrian Detection in the Wild","date":"2019-09-25","rows_on_this_dataset":1,"code_links":0,"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."}
