Wavelet Filter System and Signal Extension of Singals Subband Decomposition and Reconstruction
Gao Qing-wei · Journal of Anhui University · 1999
In the paper we analysis quadrate wavelet and biorthogonal wavelet attaining subband decomposition and perfect-reconstruction of signals throughing conjugate filter and biorthogonal filter banks, and report several method of arbitrary longth signal extension and its appling in multimedia image compress coding.
