Detailed Description

Generalized histograms up to 3 dimensions.

vtkImageAccumulate - This filter divides component space into discrete bins. It then counts the number of pixels associated with each bin. The dimensionality of the output depends on how many components the input pixels have. An input images with N components per pixels will result in an N-dimensional histogram, where N can be 1, 2, or 3. The input can be any type, but the output is always int. Some statistics are computed on the pixel values at the same time. The SetStencil and ReverseStencil functions allow the statistics to be computed on an arbitrary portion of the input data. See the documentation for vtkImageStencilData for more information.

This filter also supports ignoring pixels with value equal to 0. Using this option with vtkImageMask may result in results being slightly off since 0 could be a valid value from your input.

Set/Get - The component spacing is the dimension of each bin. This ends up being the spacing of the output "image". If the number of input scalar components are less than three, then some of these spacing values are ignored. For a 1D histogram with 10 bins spanning the values 1000 to 2000, this spacing should be set to 100, 0, 0. Initial value is (1.0,1.0,1.0).

double   
) [virtual]

Set/Get - The component origin is the location of bin (0, 0, 0). Note that if the Component extent does not include the value (0,0,0), then this origin bin will not actually be in the output. The origin of the output ends up being the same as the componenet origin. For a 1D histogram with 10 bins spanning the values 1000 to 2000, this origin should be set to 1000, 0, 0. Initial value is (0.0,0.0,0.0).

Initial value is (0.0,0.0,0.0).

Set/Get - The component extent sets the number/extent of the bins. For a 1D histogram with 10 bins spanning the values 1000 to 2000, this extent should be set to 0, 9, 0, 0, 0, 0. The extent specifies inclusive min/max values. This implies that the top extent should be set to the number of bins - 1. Initial value is (0,255,0,0,0,0)

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageAccumulate::RequestInformation ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageAccumulate::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageAccumulate::FillInputPortInformation ( int  port,
vtkInformation info 
) [protected, virtual]

These method should be reimplemented by subclasses that have more than a single input or single output. See vtkAlgorithm for more information.

Reimplemented from vtkImageAlgorithm.
