چکیده
|
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].
