Abstract: Object-oriented information extraction method has become the mainstream of automatic extraction of information in remote sensing, since it is in accord with artificial intelligence and has more approaches to geographic theories. Objectification is a key step in object-oriented automatic extraction of information, in which a segmentation image is transmitted into a vector image. The proposed method is able to assign a unique value to an object represented by a grey value in the segmentation image, at the same time, calculates some other features of this object. Using this method, many processes such as removing small region, pretreatment of vectorization can be achieved much faster.

摘要: 面向对象的遥感信息提取技术由于其更符合人脑思维方式、更容易与地学知识结合,目前已经成为遥感信息自动提取的主流方向。对象化处理是面向对象遥感信息处理的重要步骤,实现了从分割影像到对象矢量影像的转变。提出了一种快速标号方法,可以快速为分割图像中的对象赋给唯一值标签并同时统计对象的其他特征,可以显著地提高去除小班块、矢量化预处理等操作的运行速度,在对象化过程中有广阔的应用前景。
