1、Halcon算子-区域特征当我们想要提取Region时，图像处理后，往往存在几个类似的Region，此时，需要根据Reg ion的一些特殊特征，来选择指定的Regiono求 Region 指定特征值：region_features(Regions : : Features : Value)根据特征值选择区域：select_shape(Regions : SelectedRegions : Features, Operatio n, Min, Max :)Region特征一览:特征英译areaArea of the object对象的面积rowRow index of the center中心点
