In this paper, we propose a universal two-dimensional (2D) absolute-cosine chaotic model (ACCM). The 2D-ACCM is composed of a nonlinear bounded cosine function and an absolute value function. It can ...

The method is fast, simple, recursive and can be used in the design of 1D or 2D zero-phase FIR filters by imposing some ... in LU-factorization or in inversion of cosine matrices.
