It involves simultaneously detecting and localizing interesting points in an image. Keypoints, also known as interest points, are spatial locations or points in the image that define what is interesting or what stands out. They are invariant to image rotation, shrinkage, translation, distortion, etc. Keypoints examples are body joints, facial landmarks, or any other salient points in objects. Keypoints have uses in problems such as pose estimation, object detection and tracking, facial analysis, and augmented reality.\r\n\r\n<span style=\"color:grey; opacity: 0.6\">( Image credit: [PifPaf: Composite Fields for Human Pose Estimation](https://github.com/vita-epfl/openpifpaf); \"Learning to surf\" by fotologic, license: CC-BY-2.0 )</span>","description_from":"task","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","rank":"the archive's row order at snapshot; not re-ranked","rows_end_at":"2025-07-28","rows_withheld_as_spam":0,"metric_values":"the archive's strings, untouched"},"metrics":["Validation AP","Test AP"],"metric_direction":{"note":"inferred from the metric name only (the archive records no direction); null = not inferred, chart draws points only","by_metric":{"Validation AP":"higher","Test AP":"higher"}},"counts":{"rows":2,"rows_with_code":2,"rows_with_paper_page":2,"rows_dated":2,"rows_using_additional_data":0},"rows":[{"rank_in_archive_order":1,"model":"Mask R-CNN","metrics":{"Test AP":"63.1","Validation AP":"69.2"},"uses_additional_data":false,"paper_date":"2017-03-20","paper":"/paper/mask-r-cnn","paper_url":"http://arxiv.org/abs/1703.06870v3","paper_title":"Mask R-CNN","code":"https://github.com/tensorflow/models/tree/master/official/vision","n_code_links":179,"syntology":{"n_ran":42,"n_unverified":98,"n_samples":140,"n_pointer_only_licence":23}},{"rank_in_archive_order":2,"model":"Part Affinity Fields","metrics":{"Validation AP":"60.5"},"uses_additional_data":false,"paper_date":"2016-11-24","paper":"/paper/realtime-multi-person-2d-pose-estimation","paper_url":"http://arxiv.org/abs/1611.08050v2","paper_title":"Realtime Multi-Person 2D Pose Estimation using Part Affinity Fields","code":"https://github.com/CMU-Perceptual-Computing-Lab/openpose","n_code_links":61,"syntology":{"n_ran":4,"n_unverified":19,"n_samples":23,"n_pointer_only_licence":4}}],"since_archive":{"claim":"Results that newer papers report for their own method, placed here by Syntology.
