a Padding method with splitting image into windows. The operation of splitting reduces the number of padded zeros for CCG calculation, which is accelerated by GPU. b Processing time of 2295 projections matching with a 5 K × 4 K image on CPU and different types of GPUs. c Occupied memory with different window sizes and overlap settings (180, 150, and 120).
