The discrimination and the removing method of salt noise in the digital images are discussed.

However, salt & pepper noise occur during ima ge generation, communication and transformation, and affect image quality.

The median filtering method can suppress salt & pepper noise, but the image′s details are blurred at the same time.

In the digital imaging equipment,Gaussian white noise and salt & pepper noise are both common noise source.
