Methods used to make repaired quality digital image from Gaussian noise, with combination of adaptive filter algorithm and wiener filter, called Adaptive Wiener Filter. This Filter will estimate noise through the adaptation parameter such as mean and variance from degradation image. The filtering system uses Adaptive Wiener Filter better than multistage system. Analyzing the result beginning with computing MSE and PSNR value, and comparing with different method. The result of this research shows that the value of MSE with Multistage Adaptive Wiener Filter smaller than PSNR and higher than other methods filter so improve the quality of degradation image.
