  1. Here, the following abbreviations were used: NB number of blocks, n.a. not applied, BP seconds spent for block partitioning, SB seconds spent for the single block iteration, CB seconds spent for the combining of deblurred block images, IN the iteration number that attained the smallest RSE, and PC seconds spent for the parallel computation in case when NB processing units are used.
  2. The row starting with ‘ 1×1’ in NB column represents results by RL
