Paper Abstract

This paper introduces a class of M-channel linear phase perfect reconstruction filter banks with integer coefficients. The construction of these filter banks is based on a VLSI-friendly lattice structure which employs the minimum number of delay elements and robustly enforces both linear phase and perfect reconstruction properties. The lattice coefficients are parameterized as a series of lifting steps, providing fast, efficient, in-place computational of the subband coefficients. Image coding experiments show that these novel FBs are very competitive with current state-of-the-art transforms such as the 8 X 8 DCT and the wavelet transform with 9/7-tap biorthogonal floating-point wavelet.
