| 摘 要： | SAR图像存在乘性相干斑的影响，传统的图像分割方法不能很好保持图像的结构信息．文章研究了基于视觉特性的组合分割方法，该方法通过塔型方向滤波器组进行去噪，发展了各向异性的核期望转移滤波器，核的形状、尺度和方向都能自适应图像的局部结构，最后结合边缘检测对图像分割进行修正．分析和实验表明该方法对SAR图像是有效的．

| Abstract: | The multiplicative nature of the speckle noise in SAR images is a big problem in the image segmentation. The traditional algorithm (can't) obtain a better performance in keeping structural information of the image. A compounding segmentation algorithm based on vision information is proposed in this paper. The speckle noise could be denoised by pyramid directional filter banks in the image pretreatment. The authors also develop an anisotropic kernel mean shift in which the kernel's shape, scale, and orientation can adapt to the local structure of the image; and at last the authors revise the image segmentation performance via edge detection. The analysis and experimental results on SAR image demonstrate the effectiveness of this algorithm. |
