| Abstract(in English) | This paper introduces a novel impulse noise removal filter using position information, which represents the position of impulse noises on images. The noise position information(the noise position image)can be obtained from corrupted images by using the impulse detector of the PSM filter. In this paper, we try to improve noise removal performance by applying recurrent implementation to the PS-scheme filters. Moreover, the proposed filter has effectiveness to preserve edges and details on images because the proposed filter is based on the directional difference filter considering directional features(signal patterns)of image signal. We also investigate a technique(prediction)that the proccessing point is proccessed after the corrupted pixels are removed in the processing window and show that the technique works more effectively than the conventional PSM filter and the directional difference filter. First, we show the superior performance of recurrent PSM and PSH filters. Next, we investigate the estimation accuracy of processing point in case of obtaining all signals in the processing window. Finally, a novel directional difference filter based on those properties is proposed and experiment results demonstrate the effectiveness. |
