A new method of impulse de-noising is proposed based on wavelet modulus maximums. 摘要根据小波系数模极大值的特性,提出了去除脉冲噪声的一种新方法。
The fuzzy impulse noise detector using median value and neighbourhood information detects impulse noise.The impulse noise canceller uses minimum-maximum estimate method. 模糊脉冲噪声检测器用窗口内的中值与邻近像素信息来检测脉冲噪声,而脉冲消除器用最小最大值算法来计算噪声像素的估计值。
