Separable-denominator state-space realization of two-dimensional filters using a canonic form
Takao Hinamoto, Frederick W. Fairman · IEEE Transactions on Acoustics Speech and Signal Processing · 1981
In this paper a procedure is developed for the computation of a state-space realization of a two-dimensional filter. The transfer function of this realization has a separable denominator. The procedure relies on a canonic form for the state-space realization and utilizes a finite sequence of two-dimensional pulse response coefficients (Markov parameters).
