Two-dimensional (2D) recursive digital filters find applications in image processing as in medical X-ray processing. Nonsymmetric half-plane (NSHP) filters have definitely positive magnitude characteristics as opposed to quarter-plane (QP) filters. In this paper. we provide methods for stabilizing the given 2D NSHP polynomial by the planar least squares inverse (PLSI) method. https://balboasurfandsstylers.shop/product-category/changing-towel/
