Plane extraction of point cloud data plays an important role in the three-dimensional scene reconstruction, while region growing algorithm which could separate the points with specific attributes is a typical method to deal with this kind of problem. In this paper, methods of plane extraction based on region growing algorithm are studied, and they are divided into four categories according to the...
At present, there are two main types for medical CT image surface reconstruction: one is way of the slice contour, the other is voxel reconstruction, the former method is simple, easy for calculation and much classical computer graphics techniques can be used, the latter is related to complex computing. In this paper, image contours are extracted by active contour model, simplified by DP algorithm...
