一种高斯噪声组合滤波方法

In order to filter Gaussian noise effectively, a kind of combination filter method id put forward.Firstly, new wiener filter templates are definited by the filter method so as to filter the part of the Gaussian noise; Then the image is conducted two-dimensional wavelet decomposition, keeping the low frequency components, according to the characteristics of the noise distribution, new morphological filter templates are designed, and the wavelets coefficients are reconstructed; Finally, a new wavelet enhancement function is designed to improve the clarity of the image, reserve the detail information of image. Experiment results show that the filtering method is better than that of the wiener filtering and morphological filtering. It is a more practical Gaussian noise denoising method.
