Enclosing class:

opencv_core

@Namespace(value="cv")
public static class opencv_core.Algorithm
extends org.bytedeco.javacpp.Pointer

\brief 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

position

public opencv_core.Algorithm position(long position)

Overrides:

position in class org.bytedeco.javacpp.Pointer

clear

public void clear()

\brief Clears the algorithm state

write

public void write(@ByRef
                  opencv_core.FileStorage fs)

\brief Stores algorithm parameters in a file storage

write

public void write(@opencv_core.Ptr
                  opencv_core.FileStorage fs,
                  @opencv_core.Str
                  org.bytedeco.javacpp.BytePointer name)

\brief simplified API for language bindings \overload

write

public void write(@opencv_core.Ptr
                  opencv_core.FileStorage fs,
                  @opencv_core.Str
                  String name)

read

public void read(@Const @ByRef
                 opencv_core.FileNode fn)

\brief Reads algorithm parameters from a file storage

empty

@Cast(value="bool")
public boolean empty()

\brief Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

save

public void save(@opencv_core.Str
                 org.bytedeco.javacpp.BytePointer filename)

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

save

public void save(@opencv_core.Str
                 String filename)

getDefaultName

@opencv_core.Str
public org.bytedeco.javacpp.BytePointer 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.
