(69) インパルス性雑音を除去する新しい非線形ディジタルフィルタ −画像処理への応用−
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.
