摘要 中值滤波能够很好的抑制消除一些孤立的噪声点,并且还能保护图像使得图像的边缘不容易被模糊,但由于中值滤波容易把边缘点和孤立噪声点混淆,导致滤波效果不是很好,本文通过对一般的中值滤波算法进行改善,提高消噪效果。 Median fltering can suppress some isolated noise points well,and protect images so that the edges of the images are not easily blurred.However,due to the confusion between edge points and isolated noise points in median fltering,the fltering effect is not very good.In this paper,the general median fltering algorithm is improved to improve the denoising effect.
