Figure 12From: Two-dimensional integer wavelet transform with reduced influence of rounding operations Change of magnitude response caused by rounding: (a) 5/3 filter bank; (b) 9/7 Deslauriers-Dubuc filter bank; (c) 9/7 filter bank; (d) 9/7 filter bank with lifting coefficients from eq. ( 39 ) (solid: transfer function without rounding; dash, dash-dot, and dot indicate signal values v of 31, 15, and 9 used for determination of the impulse responses with rounding).
