public enum RetrievalModes

Fields

CComp = 2: retrieves all of the contours and organizes them into a two-level hierarchy. At the top level, there are external boundaries of the components. At the second level, there are boundaries of the holes. If there is another contour inside a hole of a connected component, it is still put at the top level.
External = 0: retrieves only the extreme outer contours. It sets hierarchy[i][2]=hierarchy[i][3]=-1 for all the contours.
FloodFill = 4
List = 1: retrieves all of the contours without establishing any hierarchical relationships.
Tree = 3: retrieves all of the contours and reconstructs a full hierarchy of nested contours.
