【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．更多还原

【Abstract】 This paper proposes an exponential behavior based entropy operafor for3D edge detection.The surface point can be located by the entrOPy of a iceal windowand the orientation of the surface can be decided by the coordinates of the eentroidof the window.A related fast algorithm is presented. The experimental reeedtererjfy that the method is efficient for 3D medieal images.更多还原
