However, this task exposes a weakness in deep learning models known as spectral bias, an inherent tendency to learn smooth, low-frequency functions which causes them to systematically erase the very high-frequency boundary details that are of primary interest. To resolve this conflict, we propose a framework to deeply seek object boundaries. First, we propose High-Frequency Initialized LoRA (HiFi-LoRA) to counteract spectral bias. By initializing the LoRA adaptation matrices as the optimal low-rank approximation of a high-pass filter, it fundamentally enhances the model's high-frequency perception and injects a strong preference for edges. Second, we propose the Wavelet Energy Modulation (WEM) regularizer. It guides the model to learn the intrinsic correlation between contour complexity and mask area, forcing the model to build a geometric understanding of contour morphology upon its high-frequency perception, thereby enabling the generation of boundary details commensurate with the object's scale. Experimentally, we constructed the Lunar Regolith  Segmentation Dataset (LRSD), the first large-scale benchmark with expert-annotated contours. Extensive experiments demonstrate that our method sets a new state of the art on this challenging benchmark, not only achieving top performance on regional metrics like mIoU and DSC but, more critically, drastically outperforming existing models on boundary accuracy. This work not only provides a powerful computational tool for lunar science but also offers a robust and synergistic design pattern for other fine-grained segmentation challenges.<\/jats:p>","DOI":"10.1609\/aaai.v40i12.37994","type":"journal-article","created":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T23:56:21Z","timestamp":1773791781000},"page":"10252-10260","source":"Crossref","is-referenced-by-count":0,"title":["Deeply Seeking Boundary for Lunar Regolith Segmentation"],"prefix":"10.1609","volume":"40","author":[{"given":"Yifeng","family":"Wang","sequence":"first","affiliation":[]},{"given":"Lingxin","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Lu","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[]},{"given":"Chao","family":"Xu","sequence":"additional","affiliation":[]},{"given":"Weiwei","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Junyue","family":"Tang","sequence":"additional","affiliation":[]},{"given":"Yanhong","family":"Zheng","sequence":"additional","affiliation":[]},{"given":"Yong","family":"Pang","sequence":"additional","affiliation":[]},{"given":"Shengyuan","family":"Jiang","sequence":"additional","affiliation":[]},{"given":"Yi","family":"Zhao","sequence":"additional","affiliation":[]},{"given":"Zongquan","family":"Deng","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2026,3,14]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/37994\/41956","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/37994\/41956","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T23:56:22Z","timestamp":1773791782000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/37994"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,14]]},"references-count":0,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2026,3,17]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v40i12.37994","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,14]]}}}
