摘要
非线性滤波是一种有效的噪声抑制技术,得到了广泛的应用。文中针对标准中值滤波方法存在的不足,提出自适应中值滤波方法。该方法采用一定的检测标准对图像中的噪声点进行检测,并采用改进的中值滤波方法对噪声点进行滤波。实验结果表明,此方法较标准中值滤波具有更优良的滤波性能。
As an effective processing technology, the non-linear filter is widely used. To overcome the drawbacks of the standard median filter, the adaptive median filter is proposed. With this algorithm, the noise in the image is detected in accordance with certain standard, and is removed by means of ameliorated median filter. Experiment results show that the method has a better filtering effect than the standard median filter.
