Abstract

Two-dimensional (2-D) periodically shift variant (PSV) digital filters are considered. The filters are formulated in the form of the Fornasini-Marchesini (FM) state-space model with periodic coefficients. This PSV model is then represented as a new shift-invariant system which is named the 'Kiok-Neon' model. This model has several advantages that include ease of analysis and reduced computations compared to the existing state-space models. An algorithm is developed that transforms any given 2-D PSV FM system to its equivalent 'Kiok-Neon' model. Invertibility of this model is an important consideration, especially in image scrambling applications. A condition is established for the invertibility of the 'Kiok-Neon' model of the 2-D PSV system. Also, the inverse system can be easily computed from the original.
