public class Algorithm extends Object
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: SNIPPET: snippets/core_various.cpp Algorithm

Method Detail
-
getNativeObjAddr
public long getNativeObjAddr()
-
__fromPtr__
public static Algorithm __fromPtr__(long addr)
-
getDefaultName
public String 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
-
empty
public boolean empty()
Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read- Returns:
- automatically generated
-
clear
public void clear()
Clears the algorithm state
-
save
public void save(String filename)
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
