Binomial QMFとは 意味・読み方・使い方

Orthonormal binomial quadrature mirror filter (binomial-QMF) bank with perfect reconstruction (PR) was designed by Ali Akansu, et al. published in 1990 using the family of binomial polynomials for subband decomposition of discrete-time signals . They also showed that these binomial-QMF filters are identical to the wavelet filters designed independently by Ingrid Daubechies from compactly supported orthonormal wavelet transform perspective in 1988 (Daubechies wavelet). Later, it was shown that the magnitude square functions of low-pass and high-pass binomial-QMF filters are the unique maximally flat functions in a two-band PR-QMF design framework.
