public class Algorithm
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.).
The class provides the following features for all derived classes:
Algorithm.create
). If you plan to add your own algorithms, it
is good practice to add a unique prefix to your algorithms to distinguish
them from other algorithms.
cvSetCaptureProperty()
, cvGetCaptureProperty()
,
VideoCapture.set()
and VideoCapture.get()
.
Algorithm
provides similar method where instead of integer id's
you specify the parameter names as text strings. See Algorithm.set
and Algorithm.get
for details.
Here is example of SIFT use in your application via Algorithm interface:

Sets the algorithm parameter
The method sets value of the particular parameter. Some of the algorithm parameters may be declared as read-only. If you try to set such a parameter, you will get exception with the corresponding error message.
