In this paper, we propose a novel boundary-enhanced instance segmentation (BEIS) framework that explicitly models the feature relationships across object boundaries for high-quality instance segmentation. Specifically, BEIS generates boundary-enhanced features using both intra-mask and cross-image boundary discrimination learning. The intra-mask boundary discrimination learning (IBDL) employs pixel-level discrimination learning to disentangle pixel representations along boundaries. The cross-image boundary discrimination learning (CBDL) learns a boundary-aware feature bank from training data to further boost the performance. Thus, CBDL can take advantage of boundary relations across images to enhance the quality of segmented boundaries. To focus on hard-to-segment boundaries, we propose an adaptive sampling strategy to automatically construct discriminative pairs in regions with high possibilities of confusion. Extensive experiments show BEIS outperforms on various datasets.<\/jats:p>","DOI":"10.3233\/faia240537","type":"book-chapter","created":{"date-parts":[[2024,10,17]],"date-time":"2024-10-17T12:47:17Z","timestamp":1729169237000},"source":"Crossref","is-referenced-by-count":1,"title":["Boundary-Enhanced Instance Segmentation"],"prefix":"10.3233","author":[{"given":"Fangyuan","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Software, Tsinghua University, China"},{"name":"Beijing National Research Center for Information Science and Technology (BNRist), China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianxiang","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Software, Tsinghua University, China"},{"name":"Beijing National Research Center for Information Science and Technology (BNRist), China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Wing","family":"Tai","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Dartmouth College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Software, Tsinghua University, China"},{"name":"Beijing National Research Center for Information Science and Technology (BNRist), China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2024"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA240537","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,17]],"date-time":"2024-10-17T12:47:18Z","timestamp":1729169238000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA240537"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,16]]},"ISBN":["9781643685489"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia240537","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,10,16]]}}}
