Detailed Description

template<class TInputImage, class TOutputImage>
class itk::VectorExpandImageFilter< TInputImage, TOutputImage >

Expand the size of a vector image by an integer factor in each dimension.

VectorExpandImageFilter increases the size of an image by an integer factor in each dimension using a interpolation method. The output image size in each dimension is given by:

OutputSize[j] = InputSize[j] * ExpandFactors[j]

The output values are obtained by interpolating the input image. The default interpolation type used is the VectorLinearInterpolateImageFunction. The user can specified a particular interpolation function via SetInterpolator(). Note that the input interpolator must derive from base class VectorInterpolateImageFunction.

When the LargestPossibleRegion is requested, the output image will contain padding at the upper edge of each dimension. The width of padding in the i'th dimension is (ExpandFactors[i] - 1). Users can specify the padding value used by setting the EdgePaddingValue.

This filter will produce an output with different pixel spacing that its input image such that:

OutputSpacing[j] = InputSpacing[j] / ExpandFactors[j]

The filter is templated over the input image type and the output image type.

This filter is implemented as a multithreaded filter and supports streaming.

Warning:

This filter only works for image with pixel types base on itk::Vectors. For scalar pixel images use ExpandImageFilter.

This filter assumes that the input and output image has the same number of dimensions, and that the input and output pixel types have the same vector dimension.

VectorExpandImageFilter is implemented as a multithreaded filter. Therefore, this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread" See also: ImageToImageFilter::ThreadedGenerateData(), ImageToImageFilter::GenerateData() Reimplemented from itk::ImageSource< TOutputImage >.
