中文说明：对标准中值滤波方法存在的不足，结合均值思想提出两种改进的中值滤波算法，即加 权快速中值滤波算法和加权自适应中值滤波算法，MATLAB实验证实两种方法均能更好地保 存原始图像的细节和边缘。比较这种新方法得出以下结论：加权改进中值滤波算法对低密度的 脉冲噪声去噪效果明显，对于高密度脉冲噪声去噪效果不理想，但能大大提高中值滤波的运行 速度，对数字图像实时处理意义很大
English Description：
Inadequacy of the standard method of median filter, combined with the were thought presents two improved median filtering algorithm, plusRight fast median filtering algorithm and adaptive weighted median filtering algorithm, MATLAB experiments confirmed that both methods can better keepDeposit detail and edges of the original image. This new approach came to the following conclusion: weighted improved median filter algorithm of low densityImpulse noise de-noising effect for high impulse noise de-noising effect is not ideal, but can greatly improve the running median filterThe speed of digital image processing in real time means a lot
