Rationalized procedures of FDWT/IDWT basic operations execution for DB4, DB6 and coif6 filters

In paper a rationalized approaches to Discrete Wavelet Transform (DWT) coefficients computing, based on modified algorithm of DWT base operation execution, with less multiplication operations are presented. Those several intuitive ways allow to decrease computational complexity of hardware operational units for DWT basic operation computation and provide convenient conditions for wavelet data treatment processors in reprogrammable circuits effective realization.
