An example of indexing the spatial and temporal decomposed subbands. The above figure shows the indices of the spatially decomposed subbands, in which the subband indexed by represents the subband is the -th after the -th spatial decomposition. The below figure shows the indices of the temporally decomposed subbands, in which the subband indexed by represents the subband is the -th after the -th spatial decomposition. Accordingly, any subband obtained by the MCTF can be indexed by .
