  • Abstract
    Based on the characteristic of SAR images and speckle noise, combining the direction information with multiple resolution analysis, an idea based on directional filter banks is presented in this paper. Combining with Laplacian pyramid analysis further, a method of reducing speckle noise in SAR image based on Laplacian pyramid directional filter banks is given in the paper. Comparing the results by emulation experiments, the validity of the method in this paper is proved
