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 L ee滤波器作去噪声处理 ,最后再作同态逆变换 .
In the paper, a homomorphic filtering algorithm 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.
