It's difficult to filter an image while protecting its detail. In this paper, a novel filter is proposed for detail preserving restoration of images. Corrupted pixels are detected by a multi-scale way. For the corrupted pixels, we use a kind of four direction interleaved interpolation value to replace their value. The performance of the proposed operator is(More)
Median filter has been widely used for restoration of noise image. In this paper, we present a novel adaptive fuzzy median filter to the restoration of salt & pepper impulse noise-corrupted image, which is particularly effective at removing highly impulsive noise. First a fuzzy estimation phase is based on the calculation of the sum of eight direction(More)
