ChainApproxMethod Fields |
The ChainApproxMethod type exposes the following members.
| Name | Description | |
|---|---|---|
| ChainApproxNone |
translate all the points from the chain code into points;
| |
| ChainApproxSimple |
compress horizontal, vertical, and diagonal segments, that is, the function leaves only their ending points;
| |
| ChainApproxTc89Kcos |
apply one of the flavors of Teh-Chin chain approximation algorithm
| |
| ChainApproxTc89L1 | ||
| ChainCode |
output contours in the Freeman chain code. All other methods output polygons (sequences of vertices).
| |
| LinkRuns |
use completely different contour retrieval algorithm via linking of horizontal segments of 1s. Only LIST retrieval mode can be used with this method
