Figure 3From: The biorthogonal wavelets that are redundant-free and nearly shift-insensitiveThe magnitude responds of filters F ( z ) and G ( z ) for the filters in Table2 and “bior3.9”. (a) cos(ω/2)f′(cosω), g(cosω), |cos(ω/2)f′(cosω) + g(cosω)| and |cos(ω/2)f′(cosω)−g(cosω)| for the filters in Table2, (b) the corresponding curves for wavelet “bior3.9”.Back to article page
