摘要
提出了一种自适应斑点滤波算法,它基于小波变换检测图像中的边缘点,根据检测结果结合多视处理实现斑点滤波。文章从理论上证明了其可行性,实验结果表明该方法达到了平滑均匀区域且保留边缘的目的。
An adaptive speckle filtering algorithm is proposed.It detects image points belonging to edge based on wavelet transform.Speckle are filtered according to detect results and multi-look.Feasibility of this method is proved theoretically.Ex periment results demonstrate that edges are reserved and uniform areas are smoothed simultaneously un-der the proposed algorithm.
