然后把具有相同特征的像素分割成线段对象与块对象，以这些对象为最基本的分类单元；

Then they are partitioned into image objects which are basic cells to classify map features, not single pixels.

描述曲线的直线段的数目由面积法则来决定，并且待处理的曲线将被分割成相等数目的线段。

The number of the segments is determined by an area criterion, and the curves to be matched are represented by an included angle chain of the same length.
