Description: Douglas-Peucker算法
在数字化过程中，需要对曲线进行采样简化，即在曲线上取有限个点，将其变为折线，并且能够在一定程度
上保持原有的形状。
经典的Douglas-Peucker算法描述如下：
（1）在曲线首尾两点A，B之间连接一条直线AB，该直线为曲线的弦；
（2）得到曲线上离该直线段距离最大的点C，计算其与AB的距离d；
（3）比较该距离与预先给定的阈值threshold的大小，如果小于threshold，则该直线段作为曲线的近似，该段曲线处理完毕。
（4）如果距离大于阈值，则用C将曲线分为两段AC和BC，并分别对两段取信进行1~3的处理。
（5）当所有曲线都处理完毕时，依次连接各个分割点形成的折线，即可以作为曲线的近似。

Description: 在计算机地图制图的过程中，通过各种手段获取的矢量数据往往存在各种各样的问题，需要对数据进行预处理，数据压缩是其中的一种处理方法。在计算机地图中，数据压缩的对象是线状要素中心轴线和面状要素边界数据(几何数据) ，本程序名称为道格拉斯－普克算法．-computer cartography in the process, through various means to obtain the vector data exists in a wide variety of issues, the need for data preprocessing, Data compression is one of these options. In the computer map, Data compression is targeted at the center axis of linear elements and the elements of the border facial data (geometric data) The procedure known as Douglas-Puke algorithm.

Description: When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing!
This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages:
