Abstract Some new methods for reducing the multiplying noise in the digital images, which are mainly the one of weighting and adding methods, are proposed, after that the characteristics of the noise is studied. The theory is analysed with the common model of multiplying noise and proved by the experiments with real data. It is clear that these methods have more ad-Tantages than traditional ones in processing digital images.

Key words： Digital image processing Multiplying noise Equivalent signal noise rate Weighting
