SyntaxThe GeneralizedHoughBallard type exposes the following members.
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.) |
 | CannyHighThresh |
Canny high threshold.
(Inherited from GeneralizedHough.) |
| CannyLowThresh |
Canny low threshold.
(Inherited from GeneralizedHough.) |
| CvPtr |
Native pointer of OpenCV structure
(Inherited from DisposableCvObject.) |
| DataHandle |
Gets or sets a handle which allocates using cvSetData.
(Inherited from DisposableObject.) |
| Dp |
Inverse ratio of the accumulator resolution to the image resolution.
(Inherited from GeneralizedHough.) |
| Empty |
Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read
(Inherited from Algorithm.) |
| 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.) |
| Levels |
R-Table levels.
|
| MaxBufferSize |
Maximal size of inner buffers.
(Inherited from GeneralizedHough.) |
| MinDist |
Minimum distance between the centers of the detected objects.
(Inherited from GeneralizedHough.) |
| VotesThreshold |
The accumulator threshold for the template centers at the detection stage.
The smaller it is, the more false positions may be detected.
|
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.) |
  | Create |
Creates a predefined GeneralizedHoughBallard object
|
| Detect(InputArray, OutputArray, OutputArray) |
find template on image
(Inherited from GeneralizedHough.) |
| Detect(InputArray, InputArray, InputArray, OutputArray, OutputArray) |
find template on image
(Inherited from GeneralizedHough.) |
| 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.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize |
Destructor
(Inherited from DisposableObject.) |
| 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.
(Inherited from Algorithm.) |
| 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 |
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.) |
| SetTemplate(InputArray, NullablePoint) |
set template to search
(Inherited from GeneralizedHough.) |
| SetTemplate(InputArray, InputArray, InputArray, NullablePoint) |
set template to search
(Inherited from GeneralizedHough.) |
| 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 |
Stores algorithm parameters in a file storage
(Inherited from Algorithm.) |
Fields| Name | Description | |
|---|---|---|
 | ptr |
Data pointer
(Inherited from DisposableCvObject.) |
