| 摘 要： | 提出一种用于压缩散斑噪声的同态滤波Lee滤波器级联算法。它首先对信号进行同态变换,然后用Lee滤波器作去噪声处理,最后再作动态逆变换。仿真结果表明它即保持了图像的边缘又有效地抑制了散斑噪声。

| Abstract: | A homomorphic filtering used speckle noise suppressing is proposed.It first makes the homomorphic transformation on the noisy signal,then applies lee filter to remove noise,and at the end carries out the inverse transformation.Simulation results show the algorithm can not only effectively suppress speckle noise in images but also preserve the geometrical features of images. |

| Keywords: | speckle noise suppression homomorphic filter lee filter |
