* * CV_RETR_LIST - retrieve all the contours and puts them in the list.
* * CV_RETR_CCOMP - retrieve all the contours and organizes them into two-level hierarchy:

* * :tree - retrieve all the contours and reconstructs the full hierarchy of nested contours
* * CV_RETR_TREE - retrieve all the contours and reconstructs the full hierarchy of nested contours
