A design method for the numerical design and optimization of FIR-filters for video signal processing applications is presented in this paper. The main goal of this filter design process is to achieve a high subjective quality of the filtered image. As the perception of picture quality by the human visual system depends on different filter properties in the spatial domain as well as in the frequency...
In this paper, a new mapping between the s-domain and the z-domain is reported. This method is denoted as the magnitude-invariance method (MIM). Under this mapping, it is shown that the autocorrelation function of the unit sample response of the discrete-time system is samples of the autocorrelation function of the Dirac impulse response of the analog prototype convolved with a sinc function. If the...
