The SparseMat type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Addref |
manually increments the reference counter to the header.
|
 | AllocGCHandle |
Pins the object to be allocated by cvSetData.
(Inherited from DisposableObject.) |
| AllocMemory |
Allocates the specified size of memory.
(Inherited from DisposableObject.) |
| AssignFrom(Mat) |
Assignment operator. equivalent to the corresponding constructor.
|
| AssignFrom(SparseMat) |
Assignment operator. This is O(1) operation, i.e. no data is copied
|
| AssignTo |
not used now
|
| Channels |
Returns the number of sparse matrix channels.
|
| Clear |
sets all the sparse matrix elements to 0, which means clearing the hash table.
|
| Clone |
creates full copy of the matrix
|
| ConvertTo(SparseMat, Int32, Double) |
multiplies all the matrix elements by the specified scale factor alpha and converts the results to the specified data type
|
| ConvertTo(Mat, Int32, Double, Double) |
converts sparse matrix to dense n-dim matrix with optional type conversion and scaling.
|
| CopyTo(Mat) |
converts sparse matrix to dense matrix.
|
| CopyTo(SparseMat) |
copies all the data to the destination matrix. All the previous content of m is erased.
|
| Create |
Reallocates sparse matrix.
If the matrix already had the proper size and type,
it is simply cleared with clear(), otherwise,
the old matrix is released (using release()) and the new one is allocated.
|
| Depth |
Returns the depth of sparse matrix element.
|
| Dims |
Returns the matrix dimensionality
|
| Dispose |
Releases the resources
(Inherited from DisposableObject.) |
| Dispose(Boolean) |
Releases the resources
(Overrides DisposableCvObjectDispose(Boolean).) |
| ElemSize |
returns the size of each element in bytes (not including the overhead - the space occupied by SparseMat::Node elements)
|
| ElemSize1 |
returns elemSize()/channels()
|
| Equals | (Inherited from Object.) |

|
| Hash(Int32, Int32) |
Computes the element hash value (2D case)
|
| Hash(Int32, Int32, Int32) |
Computes the element hash value (3D case)
|
