In this paper, a method for extract and reconstruction image skeleton based on mathematical morphology is presented.

提出了基于数学形态学理论来提取图象中的骨架并由骨架重建图象的方法。

The skeleton method of this paper could extract the skeletons from initial images directly due to overcome impact of noise effectively, and guarantee accuracy of skeletons.

本文的骨架算法能够有效克服噪声的影响，可对初始图像进行直接处理，保证骨架线提取的精确性。

If the threshold was initialized, this method could extract the skeleton from the noisy image.

如果通过设定一个阈值，再提取骨架，就可以滤除背景中的噪声。

So the team set about seeing if they could extract viable DNA from the skeleton, and they succeeded.
