Adaptive Noise Reduction Scheme for Salt and Pepper

Understand

In this paper, a new adaptive noise reduction scheme for images corrupted by impulse noise is presented.

• The proposed scheme efficiently identifies and reduces salt and pepper noise.
• MAG (Mean Absolute Gradient) is used to identify pixels which are most likely corrupted by salt and pepper noise that are candidates for further median based noise reduction processing.
• Directional filtering is then applied after noise reduction to achieve a good tradeoff between detail preservation and noise removal.
