摘要: In this comprehensive review article, we present the theory of symmetry in two-dimensional (2-D) filter functions and 2-D Fourier transforms. It is shown that when a frequency response possesses symmetry, realization problem becomes relatively simple. Further, has no there technique to decompose into components each which desired symmetry. This again reduces complexity design. A number design examples are illustrated.
