| Abstract: | On the basis of analyzing the de-noising principle as well as the disadvantages of several regular de-noising methods, the principle of Wiener filtering and its advantages on removing gaussian noise were researched. Experiments were carried out to compare the Wiener filtering algorithm with other classical de-noising methods. The impact of different parameters on the de-noi- siug effect of Wiener filtering was also studied. The results are assessed with standards of subjective and objective evaluation. The experimental results show that Wiener filtering achieves good performance on removing Ganssian noise, and improve the quality of image. |
