MemberDescription
CV_CHAIN_CODE
output contours in the Freeman chain code. All other methods output polygons (sequences of vertices).

CV_CHAIN_APPROX_NONE
translate all the points from the chain code into points;

CV_CHAIN_APPROX_SIMPLE
compress horizontal, vertical, and diagonal segments, that is, the function leaves only their ending points;

CV_CHAIN_APPROX_TC89_L1

CV_CHAIN_APPROX_TC89_KCOS
apply one of the flavors of Teh-Chin chain approximation algorithm

CV_LINK_RUNS
use completely different contour retrieval algorithm via linking of horizontal segments of 1s. Only CV_RETR_LIST retrieval mode can be used with this method
