摘要：一、cvApproxPoly 使用多边形逼近一个轮廓，使得顶点数目变少。算法先从轮廓选择2个最远的点，然后将2个连成一个线段，然后再查找轮廓上到线段距离最远的点，添加到逼近后的新轮廓。算法反复迭代，不断将最远的点添加到结果中。直到所有的点到多边形的最短距离小于parameter参数指定的精度。二、cvArcLength、cvContourPerimeter 作用于一个轮廓并返回其长度。三、cvContourArea 计算轮廓的面积。四、cvBoundingRect 描述矩形边界框，返回一个包围轮廓的CvRect，CvRect只能表示一个方正的长方形。五、cvMinAreaRect2 ... 阅读全文
