This is a base class for all more or less complex algorithms in OpenCV
especially for classes of algorithms, for which there can be multiple implementations. The examples
are stereo correspondence (for which there are algorithms like block matching, semi-global block
matching, graph-cut etc.), background subtraction (which can be done using mixture-of-gaussians
models, codebook-based algorithm etc.), optical flow (block matching, Lucas-Kanade, Horn-Schunck
etc.).
Here is example of SimpleBlobDetector use in your application via Algorithm interface:

empty
public boolean empty()Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read- Returns:
- automatically generated
-
save
Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).- Parameters:
filename
- automatically generated
-
getDefaultName
Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.- Returns:
- automatically generated
-
finalize
