     第17回ディジタルフィルタ信号処理シンポジウム, CD-ROM (No.D3-1), 6pages, 2002-11

 In this paper, we propose a new nonlinear digital filter to remove the impulse noise. System configuration of our proposed method is based on the sliding mode system, and we can build a robust estimator by taking advantage of this sliding mode system. Furthermore, this new technique estimates not only smoothed value but also differential value. In our previous research, this method is used in order to eliminate the impulse noise on time series data. And we confirmed with
the effectiveness of ESDS as the filter which eliminates salt-pepper impulse noise on time-series data. In this pepper, we apply ESDS to image corrupted by salt-pepper impulse noise. And we make out the effectiveness of ESDS on image data.
