WebHalcon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Region的一些特殊特征，来选择指定的Region。 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, Operation, Min, Max : ) Region特征一览： 标签: … The operator compactness responds to the course of the contour (roughness) and to holes. The value of C is clipped to 1.0, because the pixel area of a region can only be an approximation of a real circle's area. This approximation error is bigger for small regions than for large regions.
