{"url":"/dataset/poseprior","name":"PosePrior","full_name":null,"description_markdown":"Accurate modeling of priors over 3D human pose is fundamental to many problems in computer vision.\r\n\r\nMost previous priors are either not general enough for the diverse nature of human poses or not restrictive enough to avoid invalid 3D poses. We propose a physically-motivated prior that only allows anthropometrically valid poses and restricts the ones that are invalid.\r\n\r\nOne can use joint-angle limits to evaluate whether two connected bones are valid or not. However, it is established in biomechanics that there are dependencies in joint-angle limits between certain pair of bones. For example how much one can flex one’s arm depends on whether it is in front of, or behind, the back. Medical textbooks only provide joint-angle limits in a few positions and the complete configuration of pose-dependent joint-angle limits for the full body is unknown.","description_withheld":null,"homepage":"https://poseprior.is.tue.mpg.de/","introduced_date":"2015-06-01","introduced_date_note":null,"introduced_by":{"paper":"/paper/pose-conditioned-joint-angle-limits-for-3d","title":"Pose-Conditioned Joint Angle Limits for 3D Human Pose Reconstruction","first_author":"Ijaz Akhter","url":null},"license":{"name":"Software Copyright License for non-commercial scientific research purposes","url":"https://poseprior.is.tue.mpg.de/license.html"},"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"3D Human Pose Estimation","url":"/task/3d-human-pose-estimation","datasets_with_task":"/datasets/task/3d-human-pose-estimation"}],"languages":[],"variants":["PosePrior"],"data_loaders":[],"num_papers_in_archive":43,"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."}
