| 摘要: |
| 基于内容的月球影像检索面向月球探测计划获取的大量遥感数据，根据影像视觉内容，提供一种方便而高效的检索方式。为提高其检索效率，在对基于内容的月球影像检索过程进行分析的基础上，运用Petri网完成过程建模与并行化分析。提出一种基于内容的月球影像检索并行框架，并据此部署实验系统，将嫦娥月球影像等实际数据集投入其中进行检索实验。结果表明，基于内容的月球影像检索并行框架能够有效提升查询检索效率。 |

| Abstract: |
| Content-based lunar image retrieval provides a convenient and efficient way for accessing relevant lunar exploration images by their visual contents. To increase the efficiency, the process of content-based lunar image retrieval was analyzed and modeled using Petri nets, and a parallel mechanism was designed based on the model. A parallel architecture was then proposed for the content based retrieval of lunar exploration images. According to the architecture, an experimental system was implemented. Experiments upon real datasets including Chang’e lunar exploration images confirm that the proposed parallel architecture can effectively improve the constructive and retrieval efficiency. |
