提出将塔形形态算法用于抑制 SAR图像中相干斑处理 ,为减少塔形处理中由于下采样造成的信息损失 ,从并行处理的角度出发 ,对塔形形态滤波器提出了改进 ,将下采样中的各子图同时进行形态滤波处理 ,在上采样中将各子图合并。经分析和处理表明这两种算法用于 SAR图像滤波都能有效地去除相干斑噪声。与塔形形态滤波、Lee滤波器算法比较 ,采用并行算法处理后图像的各项指标有明显的改善。 In order to reduce the information loss caused by down-sampling in tower-shaped processing, a new tower-shaped algorithm is proposed to suppress the speckle in SAR images. From the perspective of parallel processing, an improvement is proposed for the tower- In the subgraph at the same time morphological filtering, the upsampled in the subgraphs combined. Analysis and processing show that these two algorithms can effectively remove the speckle noise for SAR image filtering. Compared with the pyramid shape filter and the Lee filter algorithm, the indexes of the image processed by the parallel algorithm are obviously improved.
