SyntaxThe VariationalRefinement type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | VariationalRefinement |
Create an instance of Variational Refinement.
|
Properties| Name | Description | |
|---|---|---|
 | AlgorithmPtr |
Pointer to the unmanaged cv::Algorithm
|
| Alpha |
Weight of the smoothness term
|
| Delta |
Weight of the color constancy term
|
| DenseOpticalFlowPtr |
Pointer to the unmanaged cv::DenseOpticalFlow
|
| FixedPointIterations |
Number of outer (fixed-point) iterations in the minimization procedure.
|
| Gamma |
Weight of the gradient constancy term
|
| Omega |
Relaxation factor in SOR
|
| Ptr |
Pointer to the unmanaged object
(Inherited from UnmanagedObject.) |
| SorIterations |
Number of inner successive over-relaxation (SOR) iterations in the minimization procedure to solve the respective linear system.
|
Methods| Name | Description | |
|---|---|---|
| Dispose |
The dispose function that implements IDisposable interface
(Inherited from DisposableObject.) |
 | DisposeObject |
Release the unmanaged memory associated with this Optical flow algorithm.
(Overrides DisposableObjectDisposeObject.) |
| Equals | (Inherited from Object.) |
| Finalize |
Destructor
(Inherited from DisposableObject.) |
| GetHashCode | (Inherited from Object.) |
| GetType | (Inherited from Object.) |
| MemberwiseClone | (Inherited from Object.) |
| ReleaseManagedResources |
Release the managed resources. This function will be called during the disposal of the current object.
override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object
(Inherited from DisposableObject.) |
| ToString | (Inherited from Object.) |
Fields| Name | Description | |
|---|---|---|
 | _ptr |
A pointer to the unmanaged object
(Inherited from UnmanagedObject.) |
Extension Methods| Name | Description | |
|---|---|---|
 | Calc |
Calculates an optical flow.
(Defined by DenseOpticalFlowExtensions.) |
| Clear |
Clear the algorithm
(Defined by AlgorithmExtensions.) |
| 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.
(Defined by AlgorithmExtensions.) |
| IsEmpty |
Returns true if the Algorithm is empty. e.g. in the very beginning or after unsuccessful read.
(Defined by AlgorithmExtensions.) |
| Load |
Loads algorithm from the file
(Defined by AlgorithmExtensions.) |
| LoadFromString |
Loads algorithm from a String
(Defined by AlgorithmExtensions.) |
| Read |
Reads algorithm parameters from a file storage.
(Defined by AlgorithmExtensions.) |
| Save |
Save the algorithm to file
(Defined by AlgorithmExtensions.) |
| SaveToString |
Save the algorithm to a string
(Defined by AlgorithmExtensions.) |
| Write(FileStorage) | Overloaded.
Stores algorithm parameters in a file storage
(Defined by AlgorithmExtensions.) |
| Write(FileStorage, String) | Overloaded.
Stores algorithm parameters in a file storage
(Defined by AlgorithmExtensions.) |
