This paper proposes a new noise-detection method for the restoration of images corrupted by impulsive noise. The proposed method consists of two systems. In the first system, we generate a new flag image to classify the pixels of an observed image into two types: the pixels in flat areas and edge areas, and then different noise detectors process each type of pixels classified according to the flag image. The second system verifies the pixels once detected as impulsive noise by the first system. The combination of these two systems can accurately detect the location of impulsive noise and be effectively used as a preprocessor for a noise reduction filter. Experiments show that the proposed method can accurately detect the location of impulsive noise even if the observed images are highly corrupted.
