摘要
主要针对图像的高斯噪声和椒盐噪声的去噪算法进行研究,分别使用到中值滤波、均值滤波和维纳滤波三种滤波算法。实验结果表明中值滤波对于椒盐噪声有更好的去噪效果;维纳滤波对高斯噪声有明显的作用,相比中值滤波和均值滤波,维纳滤波对高斯噪声有很好的抑制效果,与此同时,维纳滤波却容易丢失边缘信息且对椒盐噪声几乎没有去噪作用。
Analyzes the denoising algorithm based on salt, pepper noise and gaussian noise. These algorithms have median filtering, average filter and Wiener filter. The experimental results show that the median filtering has better effect for salt and pepper noise. Compared with medi- an filtering and average filter, the Wiener filter has the better effect for the Gaussian noising. However, the Wiener filter algorithm is easy to loss of edge information and almost invalidly to salt and pepper noise.
