电子科技 Electronic Science and Technology ISSN 1007-7820,CN 61-1291/TN 中提出了一种基于多尺度语义信息增强的农田地块提取网络。采用并行的多尺度特征提取模块,通过保持 特征图的高分辨率保留高精度的边缘信息,降低由下采样带来的细节损耗,缓解地块之间的黏连;使用基于 注意力机制的全局语义信息增强模块,通过获取全局语义信息增强网络的类别判断能力,减少地块提取不 完整的现象。实验结果表明,在 IoU、OA、F1-Score 评价指标上本文方法在比现有研究中具有代表性的 4 种 算法高 1%~13%。 关键词:高分辨率遥感影像;农田地块;深度学****语义分割;多尺度特征;语义信息增强;地块黏连;地块不完整 中图分类号:TP751; S127 文献标志码:A A Farmland Parcel Extraction Network Based on Multi-Scale Semantic Information Enhancement ZENG Xinxin,ZHANG Hongyan (State Key Laboratory of Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079,China) Abstract: Facing the problems of adhesion of adjacent parcels and incomplete parcels due to the high heterogeneity and the small region among neighbor parcels, in this paper, a farmland parcel extraction network based on multi- scale semantic information enhancement is proposed. To alleviate the adhesion between parcels, the multi-scale
