Abstract

In this paper, a novel design method of regular cosine-modulated filter banks (CMFB's) have been presented for image coding. After introducing a regularity constraint on lattice parameters of a prototype filter in paraunitary (PU) CMFB's, we derive a regularity condition for perfect reconstruction (PR) CMFB's. Finally, we design regular 8-channel 32-length PUCMFB and PRCMFB by a unconstrained optimization of residual lattice parameters, and several simulation results for test images are shown for evaluating the proposed image coder based on the CMFB's with one degree of regularity.
