| Tiivistelmä: | Sub-band splitting is a process which decomposes the source picture into several frequency bands by means of appropriate filters. After the sub-band splitting has been performed, bit-rate reduction must be applied. In the present study, the analysis filter uses separable two-dimensional splitting into 8X8 sub-bands, with a prototype filter having 61 taps. |
