|Abstract:||A method for designing perfect-reconstruction M-channel integer-modulated filter banks (IMFB's) is proposed. Given the filter coefficient word length, many IMFB's satisfying the perfect reconstruction conditions can be obtained. Methods to select the best IMFB for the purpose of image compression are studied, and it is demonstrated that the IMFB obtained by maximizing the coding gain is the most suitable for image coding. Simulation results show that the PSNR of the integer-modulated FIR filter bank designed by maximizing the coding gain with the AR(1) model is close to that of the real-valued cosine-modulated filter bank of the same order. © 1998 IEEE.|
