Low Bit Rate Analysis of Adaptive Synthesis Filter Banks for Image Compression

“…However, this computational complexity can be reduced to "2n-1" by combining each set of delay filters with corresponding linear phase filters only because other combinations do not significantly contribute in optimal image reconstruction [9].…”

“…Adaptive synthesis filter banks [7] have no issue of maintaining dynamic synchronization between the analysis and synthesis filters as analysis section is non adaptive, which also simply the operation of filter banks. They have the ability to improve the reconstruction quality in particular at lower bit rates, by exploiting the phase diversity of the synthesis section in an adaptive mechanism.…”
