Restoration of impulse noise corrupted images using long-range correlation
Zhou Wang, David Zhang · IEEE Signal Processing Letters · 1998
We present a new algorithm that can remove impulse noise from corrupted images while preserving details. The algorithm is fundamentally different from the traditional methods in that it can utilize information not just of a local window centered about the corrupted pixel, but also of some remote regions in the image. Computer simulations indicate that our algorithm outperforms many existing techniques.
