Scale is different for each remote sensing image analysis. To show the variety of pattern and process correctly, it is important to understand image objects scale effect in scaling courses, and to select the optimal scale for special class abstraction.
每一个遥感专题应用任务对于影像分析中尺度的需求是不一样的,要正确反映测区内格局与过程的变化特征,了解多尺度转换过程中影像对象信息的变化效应,选择特定类别信息提取的最优尺度成为面向对象影像分析中关注的重点。

凭借这些特征,影像对象可以较为容易地被识别和分类。
Using these features, image objects could be recognized and classified easily.
利用一个影像对象可以用不同比特率进行编码的特性,我们将一个影像流以不同的质量提供给用户。
The algorithms make efficient use of the ability of encoding standards such as MPEG to encode one video stream in different bit-rates providing scalable service quality to users.
与此同时,通过影像分割得到影像对象,并测量这些对象的各个特征,如光谱特征、几何特征及拓扑特征等。
Meanwhile, the whole imagery was segmented into image objects, and subsequently the features used were measured, like spectral, geometrical and topological features.
