Introduced by Shuai Shao et al. in CrowdHuman: A Benchmark for Detecting Human in a Crowd1 Jan 2018 archive 2025-07-28

CrowdHuman is a large and rich-annotated human detection dataset, which contains 15,000, 4,370 and 5,000 images collected from the Internet for training, validation and testing respectively. The number is more than 10× boosted compared with previous challenging pedestrian detection dataset like CityPersons. The total number of persons is also noticeably larger than the others with ∼340k person and ∼99k ignore region annotations in the CrowdHuman training subset.

14 shown of 14 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 161. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
