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.
