Segmentation of 3D object from complex point cloud is usually performed in 2D space by using 2D algorithms. This paper presents a novel 3D algorithm for segmentation of complex point cloud. A closed B-spline surface is selected as 3D elastic model. After initialization, control points of B-spline surface are attracted by a 3D force field and move to the surfaces of target object. 3D GVF derived from...
