Numerical Algorithm For Digital Image Enhancement And Noise Minimization

Abstract

We adopt the approach of Vogel and Oman, 1998 and introduce a Lagrange multiplier Ibiejugba, 1985, to obtain an appropriate discrete energy which we minimize, in order to minimize equivalently, the unwanted vibration (noise) associated with a digitally transmitted image. An iterative algorithm is developed for this minimization and the convergence of the algorithm is proved analytically.
