## Detailed Description

Correlation imageof the two inputs.

Date:
  2002/01/22 15:32:13

Revision:
  1.24

vtkImageCorrelation finds the correlation between two data sets. SetDimensionality determines whether the Correlation will be 3D, 2D or 1D. The default is a 2D Correlation. The Output type will be float. The output size will match the size of the first input. The second input is considered the correlation kernel.

## Member Function Documentation

vtkImageCorrelation* vtkImageCorrelation::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkImageCorrelation::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkImageTwoInputFilter.

int vtkImageCorrelation::IsTypeOf | ( | const char * | type | ) | `[static]`

| Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageTwoInputFilter.

virtual int vtkImageCorrelation::IsA | ( | const char * | type | ) | `[virtual]`

| Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageTwoInputFilter.

vtkImageCorrelation* vtkImageCorrelation::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkImageTwoInputFilter.

void vtkImageCorrelation::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkImageTwoInputFilter.

virtual void vtkImageCorrelation::SetDimensionality | ( | int |  | ) | `[virtual]`

| Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageCorrelation::GetDimensionality | ( |  | ) | `[virtual]`

| Determines how the input is interpreted (set of 2d slices ...)

void vtkImageCorrelation::ExecuteInformation | ( | vtkImageData ** | inDatas,
|  | vtkImageData * | outData
| ) | `[protected, virtual]`

| Reimplemented from vtkImageMultipleInputFilter.

virtual void vtkImageCorrelation::ComputeInputUpdateExtent | ( | int | inExt[6],
|  | int | outExt[6],
|  | int | whichInput
| ) | `[protected, virtual]`

| Reimplemented from vtkImageMultipleInputFilter.

void vtkImageCorrelation::ExecuteInformation | ( |  | ) | `[inline, protected, virtual]`

| Reimplemented from vtkImageMultipleInputFilter. Definition at line 72 of file vtkImageCorrelation.h. References vtkImageMultipleInputFilter::ExecuteInformation().

void vtkImageCorrelation::ThreadedExecute | ( | vtkImageData ** | inDatas,
|  | vtkImageData * | outData,
|  | int | extent[6],
|  | int | id
| ) | `[protected, virtual]`

| The execute method created by the subclass. This is kept public instead of protected since it is called from a non-member thread function. Reimplemented from vtkImageMultipleInputFilter.
