摘  要:文章介绍了图像增强及消噪的必要性,研究了维纳滤波的原理及实现算法,采用 MATLAB 对原始图像添加常用的噪声进行仿真实验。实验结果表明,基于维纳滤波的图像增强和消噪技术对于不同噪声的处理各有优缺点,对含有高斯噪声和均匀分布噪声图像的处理效果明显优于含有椒盐噪声的图像,并且在可控范围内随着空间模板规模的增大,维纳去噪能力也会随之增强。文章说明了如何改进常用的方法,探讨了图像增强和消噪的多种可能性,对于后续的研究具有很高的参考价值。

Abstract: This paper introduces the necessity of image enhancement and denoising, studies the principle and realization algorithm of Wiener filtering, MATLAB is used to add common noise to the original images for simulation experiment. The experimental results show that the image enhancement and denoising technologies based on Wiener filtering have their own advantages and disadvantages in processing different noises. Processing result for Image with Gaussian noise and uniformly distributed noise is obviously better than image with salt and pepper noise, and within a controllable range, as the size of the spatial template increases, the Wiener denoising capability will also be enhanced. This paper explains how to improve the common methods, and discusses several possibilities of image enhancement and denoising, which has a high reference value for the follow-up research.

Keywords: Wiener filtering; noise; MATLAB; image enhancement
