#include <itkConvolutionImageFilter.h>
Convolve a given image with an arbitrary image kernel.
This filter operates by centering the flipped kernel at each pixel in the image and computing the inner product between pixel values in the image and pixel values in the kernel. The center of the kernel is defined as where is the index and is the size of the largest possible region of the kernel image. For kernels with odd sizes in all dimensions, this corresponds to the center pixel. If a dimension of the kernel image has an even size, then the center index of the kernel in that dimension will be the largest integral index that is less than the continuous index of the image center.
The kernel can optionally be normalized to sum to 1 using NormalizeOn(). Normalization is off by default.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

ConvolutionImageFilter needs the entire image kernel, which in general is going to be a different size then the output requested region. As such, this filter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.
