The intuition is that all the layers of FPN retain useful\r\ninformation. Therefore, the proposed layer introduces non-local building blocks and attention mechanisms to boost the performance.","description_state":"present","introduced_year":null,"introduced_by":{"title":"A novel Region of Interest Extraction Layer for Instance Segmentation","paper":"/paper/a-novel-region-of-interest-extraction-layer","first_author":"Leonardo Rossi","n_authors":3,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/a-novel-region-of-interest-extraction-layer"},"source":{"url":"https://arxiv.org/abs/2004.13665v2","title":"A novel Region of Interest Extraction Layer for Instance Segmentation","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":2,"archive_num_papers":2,"papers_newest_first":[{"paper":"/paper/recursively-refined-r-cnn-instance","title":"Recursively Refined R-CNN: Instance Segmentation with Self-RoI Rebalancing","date":"2021-04-03","arxiv_id":"2104.01329","n_code_links":1,"syntology":null},{"paper":"/paper/a-novel-region-of-interest-extraction-layer","title":"A novel Region of Interest Extraction Layer for Instance Segmentation","date":"2020-04-28","arxiv_id":"2004.13665","n_code_links":5,"syntology":null}],"papers_shown":2,"tasks":[{"task":"/task/instance-segmentation","name":"Instance Segmentation","papers":2},{"task":"/task/object-detection","name":"Object Detection","papers":2},{"task":"/task/semantic-segmentation","name":"Semantic Segmentation","papers":2},{"task":"/task/segmentation","name":"Segmentation","papers":1},{"task":"/task/object-detection-1","name":"object-detection","papers":1}],"tasks_shown":5,"n_tasks":5,"usage_by_year":[{"year":"2020","papers":1},{"year":"2021","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/groie"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
