Abstract(in English) | The standard deviation of Gaussian noise is required for restoration of degradation images. At the moment, the estimating method of Gaussian noise's standard deviation is proposed by PCA or MAD value. However, these methods have the problems, such as a large amount of computation time and estimate's error. Therefore, we proposed the estimate method of Gaussian noise's standard deviation which extended MAD value. The proposed method corrects the estimation value of standard deviation by using liner expression. As a result of applying this proposed method to some degraded images, it confirmed that the standard deviation's error of this proposed method is small than conventional method. |
