Members
| Member name | Value | Description |
---|
| External | 0 |
retrieves only the extreme outer contours.
It sets `hierarchy[i][2]=hierarchy[i][3]=-1` for all the contours.
|
| List | 1 |
retrieves all of the contours without establishing any hierarchical relationships.
|
| 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.
|
| Tree | 3 |
retrieves all of the contours and reconstructs a full hierarchy
of nested contours.
