摘要
随着遥感影像数量急剧增加和相关应用的不断扩展,遥感影像的语义检索日渐受到研究者的重视。本文结合遥感影像的特点重点提出遥感影像语义检索框架,并围绕影像语义检索的各关键技术相应地展开一些分析和讨论。这些技术主要包括特征提取、相似性度量、语义标注、高维索引、相关反馈、检索性能评价等。
With the increasing number and expanding application of remote sensing image, the semantic retrieval of remote sensing image has been attached more and more importance by researchers. Combined with the characteristics of remote sensing image a framework of semantic retrieval of remote sensing images is proposed in this paper, and some analysis and discussion are made about the key technologies of image semantic retrieval which are feature extraction, similarity measurement, semantic annotation, high-dimensional indexing, relevance feedback, retrieval performance evaluation, etc.
