Study of Wavelet Domain Gaussian Mixture Model with Median Filtering Mixed Image Denoising
小波域高斯混合模型与中值滤波的混合图像去噪研究

Based on the Gaussian mixture model wavelet denoising method and combining with characteristics that median filtering has better effect on impulse noise denosing, the two methods are applyed to the image denoising which contains Gaussian pulse mixed noise. Matlab is used for algorithm simulation and the experimental results show that this approach to the denoising effect is better than simply using median filter or effect of the wavelet denoising.
