Abstract :
Stability conditions are developed for a general class of nonanticipative two-dimensional digital filters which includes, but is not limited to, spatially causal filters. The conditions relate stability of filters with rational transfer functions to the behavior of their impulse response and lead to novel stability criteria applicable in the minimum mean-square design of two-dimensional filtering operations.
