摘要
通常在实际获取的图像中存在一定的噪声 ,而噪声的存在势必影响图像的清晰度、对比度等因素 ,会直接影响到下一步的图像处理。因此 ,图像滤波技术的研究一直是国内外研究的热点。中值滤波是一种典型的非线性滤波技术 ,能有效滤除干扰噪声。文中探讨了中值滤波算法原理及其在图像处理中的应用 ,并给出了采用MATLAB仿真的实例 。
Because of the influence of impersonal condition, the images taken in practice will have yawp. Yawp can touch the definition and contrast of the images. It will affect the next process of image processing. So, the technology of image filtering is researching hotspot of inland or outland. Median filtering introduced in this paper is a nonlinear signal processing method. It is effect to filter the noise. This paper introduces its principle and its application on image processing. An example of simulation by using Matlab tools is illustrated. They have preferably practicality value.
