| 摘 要： | 在局部软阈值消噪算法的基础上,对水平和垂直方向的高频系数采用模糊中值滤波进行改进,提出一种基于小波变换和模糊中值滤波的消除高斯噪声和盐椒噪声的新算法,并对该算法采用Matlab6.5做仿真实验,将该算法与小波全局软阈值去噪算法、局部软阈值去噪算法和小波包阈值去噪算法进行比较.结果显示,该算法具有更稳健的去噪性能,而且能较好地保留边缘信息.

| Abstract: | The high-frequency coefficients in the horizontal and vertical directions are treated with the fuzzy middle filter based on the soft threshold de-noised algorithm. An algorithm for removing Gaussian noise and salt-pepper noise is proposed based on wavelet transform and fuzzy midian filter. The simulation experiment is done adopting Matlab 6.5. The proposed algorithm is effective both in reserving the edge and in removing noise in compared with wavelet whole soft thresholding de-noise,part soft thresholding de-noise and wavelet packets thresholding de-noise. |
