高分辨率遥感影像能够提供详细的地面信息,具有复杂的空间结构特征。有效地描述和建模这种结构特征对实现影像解译、目标识别与提取以及场景理解等具有重要的作用。首先介绍了高分影像结构特征的概念和内涵,将结构特征划分为像元结构、目标结构和场景结构3个层次;然后对高分影像结构特征描述与建模方法进行了系统的综述,介绍了这些方法的基本思想、分析了其研究现状,并指出了存在的一些问题;最后给出了总结和展望。

The high resolution remote sensing images can provide detailed ground information, and they have complex spatial structural features. Effectively describing and modeling them will play an important role in better realizing the tasks such as image interpretation, object recognition and extraction, scene understanding, and so on. This paper firstly introduces the concept and properties of spatial structural features, and divides the spatial structural feature into three levels: pixel structure, object structure and scene structure. Then, a systematic review on recent development of spatial structural feature description and modeling methods is presented. The review focuses on the basic principles and research status of these methods, and some advantages and drawbacks are pointed out. Finally, conclusions are drawn and future research directions are discussed.
