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.) |
 | Compute(InputArray, KeyPoint, OutputArray) |
Compute the descriptors for a set of keypoints in an image.
(Inherited from Feature2D.) |
| Compute(IEnumerableMat, KeyPoint, IEnumerableMat) |
Compute the descriptors for a keypoints collection detected in image collection.
(Inherited from Feature2D.) |
 | Create |
Construct GFTT processor
|
| Detect(InputArray, Mat) |
Detect keypoints in an image.
(Inherited from Feature2D.) |
| Detect(Mat, Mat) |
Detect keypoints in an image.
(Inherited from Feature2D.) |
| Detect(IEnumerableMat, IEnumerableMat) |
Detect keypoints in an image set.
(Inherited from Feature2D.) |
| DetectAndCompute |
Detects keypoints and computes the descriptors
(Inherited from Feature2D.) |
| Dispose |
Releases the resources
(Inherited from DisposableObject.) |
| Dispose(Boolean) |
Releases the resources
(Inherited from DisposableObject.) |
| DisposeManaged |
Releases managed resources
(Overrides DisposableObjectDisposeManaged.) |
| DisposeUnmanaged |
releases unmanaged resources
(Inherited from DisposableCvObject.) |
| Empty |
Return true if detector object is empty
(Inherited from Feature2D.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize |
Destructor
(Inherited from DisposableObject.) |
| GetDefaultName | (Inherited from Feature2D.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| NotifyMemoryPressure |
Notifies the allocated size of memory.
(Inherited from DisposableObject.) |
| Read(String) | (Inherited from Feature2D.) |
| Read(FileNode) |
Reads algorithm parameters from a file storage
(Inherited from Algorithm.) |
| Save |
Saves the algorithm to a file.
In order to make this method work, the derived class must
implement Algorithm::write(FileStorage fs).
(Inherited from Algorithm.) |
| ThrowIfDisposed |
If this object is disposed, then ObjectDisposedException is thrown.
(Inherited from DisposableObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Write(String) | (Inherited from Feature2D.) |
| Write(FileStorage) |
Stores algorithm parameters in a file storage
(Inherited from Algorithm.) |
Fields| Name | Description | |
