| Abstract: | In this paper, multiplication model of speckle image in imaging lidar is analyzed, and then suppression processing for the speckle image is finished by homomorphic wavelet filter. The experimental results show that this filter can suppress effectively the speckle noise and keep the image edge. Meanwhile, the experiment results prove that multiplication model is useful for speckle image. |
