/** \class CPUImageToGPUImageFilter
*
* \brief class to abstract the behaviour of the GPU filters.
*
* CPUImageToGPUImageFilter is the GPU version of ImageToImageFilter.
* This class can accept both CPU and GPU image as input and output,
* and apply filter accordingly. If GPU is available for use, then
* GPUGenerateData() is called. Otherwise, GenerateData() in the
* parent class (i.e., ImageToImageFilter) will be called.
