Integer to integer mapping wavelet filter bank with adaptive number of zero moments

摘要: An efficient realization of a two-channel wavelet filter bank that maps integers to with an adaptive number zero moments is presented. Filters more result in better representation the smooth parts analyzed signal, while fewer are for transients and singularities. The proposed based on lifting scheme enables mapping integer signals coefficients, preserving perfect reconstruction property. derived from method fixed design, using Lagrange interpolation samples time domain. adaptation criterion computed which is, under some restrictions, reproducible side. Quantization introduces non-predictable components coefficients thus influencing behavior algorithm. Adaptation interval used reduce variance parameters.
