WFB2DEC 2-D Wavelet Filter Bank Decomposition y = wfb2dec(x, h, g) Input: x: input image h, g: lowpass analysis and synthesis wavelet filters Output: x_LL, x_LH, x_HL, x_HH: Four 2-D wavelet subbands Make sure filt

完全重构以及近似完全重构滤波器组设计程序。 -The goal is to design M analysis and synthesis FIR filters so that the analysis filters satisfy some frequency specifications and the filter bank(almost) meets the perfect reconstruction (PR) conditions. The algorithm can
