Offset learning follows the “fully convolutional” spirit. In the top branch, a convolutional layer generates the full spatial resolution offset fields. For each RoI (also for each class), PS RoI pooling is applied on such fields to obtain normalized offsets, which are then transformed to the real offsets, in the same way as in deformable RoI pooling.","description_state":"present","introduced_year":null,"introduced_by":{"title":"Deformable Convolutional Networks","paper":"/paper/deformable-convolutional-networks","first_author":"Jifeng Dai","n_authors":7,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/deformable-convolutional-networks"},"source":{"url":"http://arxiv.org/abs/1703.06211v3","title":"Deformable Convolutional Networks","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":"RoI Feature Extractors","url":"/methods/category/roi-feature-extractors","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/deformable-convolutional-networks","title":"Deformable Convolutional Networks","date":"2017-03-17","arxiv_id":"1703.06211","n_code_links":38,"syntology":{"ran":3,"of":9,"unverified":6,"pointer_only":3}}],"papers_shown":1,"tasks":[{"task":"/task/object-detection","name":"Object Detection","papers":1},{"task":"/task/semantic-segmentation","name":"Semantic Segmentation","papers":1},{"task":"/task/vessel-detection","name":"Vessel Detection","papers":1}],"tasks_shown":3,"n_tasks":3,"usage_by_year":[{"year":"2017","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/deformable-position-sensitive-roi-pooling"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
