RESTORATION OF IMPULSE NOISE-CORRUPTED IMAGES USING LONG-RANGE CORRELATION

In this letter, we present a new algorithm that can remove impulse noi se from corrupted images while preserving details. The algorithm is fu ndamentally different from the traditional methods in that it can util ize information not just of a local window centered about the corrupte d pixel, but also of some remote regions in the image, Computer simula tions indicate that our algorithm outperforms many existing techniques .
