{"url":"/method/orn","slug":"orn","name":"ORN","full_name":"Orientation Regularized Network","full_name_withheld":false,"description_markdown":"**Orientation Regularized Network** (ORN) is a multi-view image fusion technique for pose estimation. It uses IMU orientations as a structural prior to mutually fuse the image features of each pair of joints linked by IMUs. For example, it uses the features of the elbow to reinforce those of the wrist based on the IMU at the lower-arm.","description_state":"present","introduced_year":null,"introduced_by":{"title":"Fusing Wearable IMUs with Multi-View Images for Human Pose Estimation: A Geometric Approach","paper":"/paper/fusing-wearable-imus-with-multi-view-images","first_author":"Zhe Zhang","n_authors":4,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/fusing-wearable-imus-with-multi-view-images"},"source":{"url":"https://arxiv.org/abs/2003.11163v2","title":"Fusing Wearable IMUs with Multi-View Images for Human Pose Estimation: A Geometric Approach","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"Pose Estimation Blocks","url":"/methods/category/pose-estimation-blocks","pwc_aliases":[]}],"n_papers_tagged":2,"archive_num_papers":2,"papers_newest_first":[{"paper":null,"title":"Selectivity gain in olfactory receptor neuron at optimal odor concentration","date":"2025-04-14","arxiv_id":"2504.10401","n_code_links":0,"syntology":null},{"paper":"/paper/fusing-wearable-imus-with-multi-view-images","title":"Fusing Wearable IMUs with Multi-View Images for Human Pose Estimation: A Geometric Approach","date":"2020-03-25","arxiv_id":"2003.11163","n_code_links":1,"syntology":{"ran":3,"of":3,"unverified":0,"pointer_only":0}}],"papers_shown":2,"tasks":[{"task":"/task/2d-pose-estimation","name":"2D Pose Estimation","papers":1},{"task":"/task/3d-absolute-human-pose-estimation","name":"3D Absolute Human Pose Estimation","papers":1},{"task":"/task/3d-human-pose-estimation","name":"3D Human Pose Estimation","papers":1},{"task":"/task/pose-estimation","name":"Pose Estimation","papers":1}],"tasks_shown":4,"n_tasks":4,"usage_by_year":[{"year":"2020","papers":1},{"year":"2025","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/orn"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
