基于自适应数学形态学的医学图像边缘连接
Medical Image Edge Link Based on Adaptive Mathematical Morphology
【摘要】 在介绍了数学形态学基本原理的基础上,阐述了自适应数学形态学,并将之应用于有中断间隙的医学图像边缘连接。它根据边缘的斜率、曲率等特性适当调节椭圆结构元素的大小和方向,并通过自适应膨胀运算使得中断的边缘沿着它们的斜率方向延伸而最终连接起来。实验结果表明这一方法是有效的。
【Abstract】 This paper sets forth adaptive mathematical morphology methods after introducing basic theories of mathematical morphology.The method is used to link medical image edge which is discontinuous with some gaps.Broken edges are extended and linked along their slope directions by using the adaptive dilation operation.The size and orientation of elliptical structuring elements are adjusted according to the slope,curvature and other correlative characteristics of edges.The experimental results show that the method is effective.
