Paper Abstract

This paper is concerned with the development of a two-dimensional (2-D) adaptive filtering using block diagonal least mean squared (BDLMS) method. In this adaptive filtering scheme, the image is scanned and processed block by block in a diagonal fashion, and the filter weights are adjusted once per each block rather than once per each pixel. As a result, this method takes into account the correlations of the pixels along both vertical and horizontal directions. The properties of this 2-D adaptive filter, including convergence behavior, adaptation speed, and adaptation accuracy, have been studied. Simulation results are presented which indicate the effectiveness of the 2-D BDLMS when used for image enhancement and estimation applications.
