In recent years, numerous studies have leveraged frequency-domain methods to aid in camouflage target detection by utilizing frequency-domain information. However, current methods based on the frequency domain cannot effectively capture the boundary information between disguised objects and the background. To address this limitation, we propose a Laplace transform-guided camouflage object detection network called the Self-Correlation Cross Relation Network (SeCoCR). In this framework, the Laplace-transformed camouflage target is treated as high-frequency information, while the original image serves as low-frequency information. These are then separately input into our proposed Self-Relation Attention module to extract both local and global features. Within the Self-Relation Attention module, key semantic information is retained in the low-frequency data, and crucial boundary information is preserved in the high-frequency data. Furthermore, we design a multi-scale attention mechanism for low- and high-frequency information, Low-High Mix Fusion, to effectively integrate essential information from both frequencies for camouflage object detection. Comprehensive experiments on three COD benchmark datasets demonstrate that our approach significantly surpasses existing state-of-the-art frequency-domain-assisted methods.<\/jats:p>","DOI":"10.3389\/frai.2025.1732820","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T06:31:22Z","timestamp":1768372282000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Laplace-guided fusion network for camouflage object detection"],"prefix":"10.3389","volume":"8","author":[{"given":"Jiangxiao","family":"Zhang","sequence":"first","affiliation":[{"name":"Xingtai University","place":["Xingtai, HeBei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Gao","sequence":"additional","affiliation":[{"name":"Xingtai University","place":["Xingtai, HeBei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengmei","family":"He","sequence":"additional","affiliation":[{"name":"Xingtai University","place":["Xingtai, HeBei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xingtai University","place":["Xingtai, HeBei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,14]]},"reference":[{"key":"B1","first-page":"4548","article-title":"\u201cStructure-measure: a new way to evaluate foreground maps,\u201d","volume-title":"Proceedings of the IEEE International Conference on Computer Vision","author":"Fan","year":"2017"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.24963\/ijcai.2018\/97","article-title":"Enhanced-alignment measure for binary foreground map evaluation","author":"Fan","year":"2018","journal-title":"arXiv"},{"key":"B3","doi-asserted-by":"publisher","first-page":"6024","DOI":"10.1109\/TPAMI.2021.3085766","article-title":"Concealed object detection","volume":"44","author":"Fan","year":"2021","journal-title":"IEEE Trans.
