提出改进分块阈值的SAR图像分割算法,该算法不但能够充分利用图像的局部细节信息,而且利用子图像块上边和左边子图像块的统计特征,增加子图像块间的连续性限制条件。通过试验对比,证明本文提出的算法能够得到更好的分割效果。
This paper proposes an improved SAR segmentation algorithm which can not only make full use of the local detail information of image, but also uses the statistical features of the upper and left sub-image blocks to increase the continuity restriction between sub-image blocks. The experimental results show that the proposed algorithm can get a better segmentation result.
