Abstract :
Most of the stability results of 2-D discrete systems using the Lyapunov method and the state-space approach are reviewed. The stability of m-dimensional systems is studied through classification of various regions of analyticity, and several theorems and algebraic tests for checking these regions are reviewed. A stability test is presented for two-dimensional systems using the bilinear continued fraction expansion. Numerical examples are presented which support the results. The present study is pertinent to the analysis of the stability of two-dimensional filters, used extensively in image processing.<>
