摘要： 提出了一种基于指数特性的三维边界检测熵算子,通过局部窗口的熵来确定物体表面点位置,再通过窗口重心坐标确定表面方向,并给出了相应的快速算法.实验结果表明这种方法对三维医学图象是有效的.

Abstract: This paper proposes an exponential behavior based entropy operafor for 3D edge detection.The surface point can be located by the entropy of a local window and the orientation of the surface can be decided by the coordinates of the centroid of the window.A related fast algorithm is presented. The experimental results verify that the method is efficient for 3D medical images.

Key words: three-dimensional image, entropy, moment, surface detection
