Syntax
The SVD type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | SVD |
the default constructor
|
| SVD(InputArray, SVDFlag) |
the constructor that performs SVD
|
Properties
| Name | Description | |
|---|---|---|
 | AllocatedMemory |
Gets or sets a memory address allocated by AllocMemory.
(Inherited from DisposableObject.) |
| AllocatedMemorySize |
Gets or sets the byte length of the allocated memory
(Inherited from DisposableObject.) |
 | CvPtr |
Native pointer of OpenCV structure
(Inherited from DisposableCvObject.) |
| IsDisposed |
Gets a value indicating whether this instance has been disposed.
(Inherited from DisposableObject.) |
| IsEnabledDispose |
Gets or sets a value indicating whether you permit disposing this instance.
(Inherited from DisposableObject.) |
| U |
eigenvalues of the covariation matrix
|
| Vt |
mean value subtracted before the projection and added after the back projection
|
| W |
eigenvalues of the covariation matrix
|
Methods
| Name | Description | |
|---|---|---|
 | AllocGCHandle |
Pins the object to be allocated by cvSetData.
(Inherited from DisposableObject.) |
| AllocMemory |
Allocates the specified size of memory.
(Inherited from DisposableObject.) |
| BackSubst(InputArray, OutputArray) |
performs back substitution, so that dst is the solution or pseudo-solution of m*dst = rhs, where m is the decomposed matrix
|
 | BackSubst(InputArray, InputArray, InputArray, InputArray, OutputArray) |
performs back substitution
|
| Compute(InputArray, OutputArray, SVDFlag) |
computes singular values of a matrix
|
| Compute(InputArray, OutputArray, OutputArray, OutputArray, SVDFlag) |
decomposes matrix and stores the results to user-provided matrices
|
| Dispose |
Releases the resources
(Inherited from DisposableObject.) |
| Dispose(Boolean) | Releases the unmanaged resources used by the SVD and optionally releases the managed resources (Overrides DisposableCvObjectDispose(Boolean).) |
| Equals | (Inherited from Object.) |
| Finalize |
Destructor
(Inherited from DisposableObject.) |
| GetHashCode | (Inherited from Object.) |
| GetType | (Inherited from Object.) |
| MemberwiseClone | (Inherited from Object.) |
| NotifyMemoryPressure |
Notifies the allocated size of memory.
(Inherited from DisposableObject.) |
| Run |
the operator that performs SVD. The previously allocated SVD::u, SVD::w are SVD::vt are released.
|
| SolveZ |
finds dst = arg min_{|dst|=1} |m*dst|
|
| ThrowIfDisposed |
If this object is disposed, then ObjectDisposedException is thrown.
(Inherited from DisposableObject.) |
| ToString | (Inherited from Object.) |
Fields
| Name | Description | |
|---|---|---|
 | dataHandle |
Gets or sets a handle which allocates using cvSetData.
(Inherited from DisposableObject.) |
| ptr |
Data pointer
(Inherited from DisposableCvObject.) |
