| Abstract(in English) | Kalman filtering approach, which is one of the methods to remove some additive noises, can be adaptive for statistical property of the image since it exploits the image modeling. To remove the noise, in general, the Kalman filtering requires a complex procedure to estimate parameters such as statistics of the original image and property of the observed noise. So far, a parameter estimation method was proposed, however, its performance of impulsive noise removal is not enough high because this method aims at removing the Gaussian noise. In this report, we propose a method to estimate parameters in order to remove both Gaussian noise and also impulsive noise by using nonlinear technique. Simulation results show that the proposed method improves performance of impulsive noise removal by approximately 30% in MSE (mean square error) compared to the conventional method keeping enough performance of Gaussian noise removal. |
