large area target meaning in Chinese
大面积目标
Examples
- The remote sensing imagery change detection can be categorized into three classes according to the aims of the processing : the change detection of the specific targets , such as changes of the airports , the bridges , the harbors , the missile bases etc . ; the change detection of the linear shape targets , such as changes of the roads , the airports , the buildings and the other linear targets whose outlines can be described by some lines ; the change detection of large area targets , such as the changes of the cover of some region , the development of the cities , the disaster evaluation of the floods and so on
遥感图像变化检测方法(简称变化检测)根据处理目标要求可以分为三类：特定类目标的变化检测，如机场、桥梁、港口、导弹基地等目标的变化检测；线性体目标的变化检测，如道路、机场、桥梁和一般建筑物等目标的变化检测；大面积目标的变化检测，如某地域的植被变化、城市的发展、洪水灾害评估等。本文系统地研究了基于模式识别知识检测特定类目标、线性体目标和大面积目标变化的变化检测方法。 - The change detection based on the clustering of the imagery is proposed to achieve change detection of the large area targets . the steps of this change detection method are : registering the multi - date image pairs , clustering the image pairs respectively , finding differences of the clustered - image pair , marking the differences using the striking colors in the copies of the image pair
对于检测大面积目标的变化，本文使用基于图像聚类的变化检测方法，实现步骤为：多时相图像配准、分别聚类参考图像和检测图像、寻找参考图像和检测图像聚类结果中具有类别差异的像素、在原始图像的副本中用醒目颜色标注变化部分。
