A New Method for Generating Image Correlated Noise
() Abstract
A new method for generating image correlated noise is proposed. Correlated noise is obtained by filtering white noise.The expression of correlated noise's autocorrelation function and the relationship between the parameter of filter and the correlation length of correlated noise are studied. Experiments show that using this new method can generate image correlated noise successfully.
