This paper describes the theory of two-dimensional digital filters that are pseudopassive with respect to the &-norm of the state vector. As the classical pseudopassive digital filters are a subclass of these filters, the respective theorems referred to stability are also generalized. It is shown th

Taking advantage of a special class ofmultiplierless one-dimensional digitaljilters (1,2), which were designed with coeflcients which are powers of two, it is possible to design twodimensional digitaljlters, which also possess powers of two coejicients. The stability of these filters is considered a
The paper presents a technique to compute the parameters of the state-space model of the two-dimensional pseudolossless (e.g. wave or orthogonal) digital filter that best approximates a given spatial response. The search for the optimal solution is performed using an unconstrained optimization algor
