SyntaxThe BlockMeanHash type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | BlockMeanHash | Initializes a new instance of the BlockMeanHash class |
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.) |
| 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.) |
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.) |
 | Compare |
Compare the hash value between inOne and inTwo
(Inherited from ImgHashBase.) |
| Compute |
Computes block mean hash of the input image
(Overrides ImgHashBaseCompute(InputArray, OutputArray).) |
 | Create |
Create BlockMeanHash object
|
| Dispose |
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.) |
| GetMean | |
| 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.) |
| SetMode | |
| 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 | |
|---|---|---|
 | dataHandle |
Gets or sets a handle which allocates using cvSetData.
(Inherited from DisposableObject.) |
| ptr |
Data pointer
(Inherited from DisposableCvObject.) |
