ChainApproxMethod Enumeration
contour approximation method

Namespace:  Emgu.CV.CvEnum
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public enum ChainApproxMethod
  Member nameValueDescription
ChainCode0 output contours in the Freeman chain code. All other methods output polygons (sequences of vertices).
ChainApproxNone1 translate all the points from the chain code into points;
ChainApproxSimple2 compress horizontal, vertical, and diagonal segments, that is, the function leaves only their ending points;
ChainApproxTc89Kcos4 apply one of the flavors of Teh-Chin chain approximation algorithm
LinkRuns5 use completely different contour retrieval algorithm via linking of horizontal segments of 1s. Only LIST retrieval mode can be used with this method
