#include <itkGPUDataManager.h>
GPU memory manager implemented using OpenCL. Required by GPUImage class.
This class serves as a base class for GPU data container for GPUImage class, which is similar to ImageBase class for Image class. However, all the image-related meta data will be already stored in image class (parent of GPUImage), therefore we did not name it GPUImageBase. Rather, this class is a GPU-specific data manager that provides functionalities for CPU-GPU data synchronization and grafting GPU data.
