{"url":"/method/centermask","slug":"centermask","name":"CenterMask","full_name":"CenterMask","full_name_withheld":false,"description_markdown":"**CenterMask** is an anchor-free instance segmentation method that adds a novel [spatial attention-guided mask](https://paperswithcode.com/method/spatial-attention-guided-mask) (SAG-Mask) branch to anchor-free one stage object detector ([FCOS](https://paperswithcode.com/method/fcos)) in the same vein with [Mask R-CNN](https://paperswithcode.com/method/mask-r-cnn). Plugged into the FCOS object detector, the SAG-Mask branch predicts a segmentation mask on each detected box with the spatial attention map that helps to focus on informative pixels and suppress noise.","description_state":"present","introduced_year":null,"introduced_by":{"title":null,"paper":null,"first_author":null,"n_authors":0,"url_abs":null,"archive_paper_url":null},"source":{"url":"https://arxiv.org/abs/1911.06667v6","title":"CenterMask : Real-Time Anchor-Free Instance Segmentation","url_on_a_paper_host":true},"code_snippet_url":"https://github.com/youngwanLEE/CenterMask","code_snippet_url_on_a_code_host":true,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"Instance Segmentation Models","url":"/methods/category/instance-segmentation-models","pwc_aliases":[]}],"n_papers_tagged":4,"archive_num_papers":null,"papers_newest_first":[{"paper":"/paper/polite-teacher-semi-supervised-instance","title":"Polite Teacher: Semi-Supervised Instance Segmentation with Mutual Learning and Pseudo-Label Thresholding","date":"2022-11-07","arxiv_id":"2211.03850","n_code_links":0,"syntology":null},{"paper":null,"title":"Intelligent detect for substation insulator defects based on CenterMask","date":"2022-08-31","arxiv_id":"2208.14598","n_code_links":0,"syntology":null},{"paper":null,"title":"CenterMask: single shot instance segmentation with point representation","date":"2020-04-09","arxiv_id":"2004.04446","n_code_links":0,"syntology":null},{"paper":"/paper/centermask-real-time-anchor-free-instance-1","title":"CenterMask : Real-Time Anchor-Free Instance Segmentation","date":"2019-11-15","arxiv_id":"1911.06667","n_code_links":8,"syntology":{"ran":1,"of":2,"unverified":1,"pointer_only":2}}],"papers_shown":4,"tasks":[{"task":"/task/instance-segmentation","name":"Instance Segmentation","papers":3},{"task":"/task/segmentation","name":"Segmentation","papers":3},{"task":"/task/semantic-segmentation","name":"Semantic Segmentation","papers":3},{"task":"/task/semi-supervised-instance-segmentation","name":"Semi-Supervised Instance Segmentation","papers":2},{"task":"/task/defect-detection","name":"Defect Detection","papers":1},{"task":"/task/object","name":"Object","papers":1},{"task":"/task/object-detection","name":"Object Detection","papers":1},{"task":"/task/panoptic-segmentation","name":"Panoptic Segmentation","papers":1},{"task":"/task/pseudo-label","name":"Pseudo Label","papers":1},{"task":"/task/real-time-object-detection","name":"Real-Time Object Detection","papers":1},{"task":"/task/real-time-instance-segmentation","name":"Real-time Instance Segmentation","papers":1}],"tasks_shown":11,"n_tasks":11,"usage_by_year":[{"year":"2019","papers":1},{"year":"2020","papers":1},{"year":"2022","papers":2}],"row_source":"embedded","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/centermask"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
