基于弹性尺度的有向生长法的弥散型区域分割

Diffused Region Segmentation Based on Directed Growth Method with Elastic Scale

从数学形态学膨胀法的基本概念出发,提出使用弹性尺度的结构元素进行有向膨胀(生长)的思想和算法,即在一次膨胀中,结构元素的尺度或为零,或为小于阈值的某个值,这取决于待膨胀处理是否处于区域边际和相离点间的欧氏距离,经这种弹性尺度的有向生长算法的多次运用,弥散型的、形态多变的台风螺旋云带被成功地分割出来.

On the basis of the fundarental concept of expansion in mathematical morphology,the idea and algorithm of directed growth with structure elements of elastic scale have been put forward.The scale of the structure element is equal to zero or less then the threshold value in one expansion,which depends on the Euclidean distance between the adjacent points and whether the area for expansion is on the boundary or not.With multiple applications of the directed growth algorithm with elastic scale,the diffused and spiral typhoon cloud bands,which were variable in form,were successfully segmented.
