| Abstract(in English) | In this study, we investigate a noise estimation method for low-level Gaussian noise with a standard deviation of less than 10. Although various methods for estimating Gaussian noise have been proposed in the past, noise estimation of low-level Gaussian noise has large errors in images with many edge and detail signals. In this paper, we consider applying the epsilon filter to the noise estimation method in order to consider the effects of edge and detail signals, and then changing the value of epsilon in order to consider the relationship between noise level and edge and detail signals. This relationship is then estimated using an approximation function, and machine learning is used to determine the relationship between noise level and edge/detail signal by changing the epsilon value. We then estimate this relationship using an approximation function and investigate whether it is possible to obtain the standard deviation of low-level Gaussian noise superimposed on the final image by using machine learning based on the situation of the approximation function for various images. It is confirmed that estimated noise value obtained by the proposed method is better than that by conventional methods. |
