EURASIP Journal on Applied Signal Processing 2003:9, 914–921 c 2003 Hindawi Publishing Corporation The PLSI Method of Stabilizing Two-Dimensional Nonsymmetric Half-Plane Recursive Digital Filters N. Gangatharan Faculty of Engineering, Multimedia University, Jalan Multimedia, 63100 Cyberjaya, Selangor, Malaysia Email: n.gangatharan@mmu.edu.my P. S. Reddy Faculty of Engineering, Multimedia University, Jalan Multimedia, 63100 Cyberjaya, Selangor, Malaysia Email: subbarami.reddy@mmu.edu.my Received 19 April 2002 and in revised form 19 February 2003 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...
