摘要: 把Wiener 滤波和小波变换结合起来,提出了一种小波-Wiener 滤波去噪算法. 仿真结果表明,利用该算法去噪后的图像主观质量和峰值信噪比比Wiener 滤波去噪和小波变换门限去噪后的图像都要好.

Abstract: A wavelet-Wiener denoising algorithm is proposed by combining the wavelet transform together with the Wiener filtering. Simulation results show that this new algorithm yields better results, both visually and in terms of PSNR(peak signal-to-noise ratio), than the Wiener filtering and wavelet thresholding.

Key words: wavelet denoising, wavelet transform, Wiener filter, image processing
