摘要
针对合成孔径声呐图像相干斑抑制难的问题,提出了一种改进的Lee滤波相干斑抑制算法。该方法将Lee滤波与中值滤波相结合,能够在保持图像边缘细节的同时有效消除相干斑。最后通过对真实合成孔径声呐图像相干斑抑制试验验证了所提方法的有效性。
An improved Lee filter algorithm is proposed for the image speckle reduction of synthetic aperture sonar.The proposed algorithm combines the advantage of Lee filter and median filter,which can maintain the edge of image and remove the speckle effectively.The feasibility of the proposed method is verified through experiment of real synthetic aperture sonar image speckle reduction.
