Since three-dimensional (3-D) subband coding has been introduced, most researches on 3-D subband coding perform temporal filtering first. In this paper, however, we investigate the best permutation strategy for temporal, vertical, and horizontal filtering to minimize the requirement of delay elements and find that the results are opposite to our expectation.
