一种改进的自适应中值滤波算法研究

非线性滤波是一种有效的噪声抑制技术，已得到了广泛的应用。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法具有更优良的滤波性能。

Research of an Improved Adaptive Median Filtering Algorithm

Non-linear filtering is an effective noise restraining technology and has been widely used. To overcome the drawbacks of the standard median filtering method, the adaptive median filtering method is proposed. In the algorithm, the noise in the image is detected by using certain standard, and the noise is removed by means of ameliorated median filtering method. Results of experiment show that the method has a better filtering effect than the standard median filtering method.
