Abstract
In this paper, a new scheme of recursive two-dimensional (2D) adaptive digital filter is presented. It consists of a forward section, a feedback section, and decision block. A little complexity increase from [10] is used by adding adaptive quantizer to predictor error. Each section is realized as conventional non-recursive adaptive filter. Either 2D adaptive LMS or sign function algorithm can be used for adaptation. The proposed recursive filter operates as a 2D adaptive line enhancer (ALE) for images contaminated with noise. Its performance is compared with that given in [1].
