摘要: Thinning algorithms on binary images are used to generate skeletons that preserve the same connectivity structures as objects in original images. Two kinds of may be appropriate for 3D thinning algorithms: digital curves and surfaces. We propose two (18, 6) One algorithm generates other Both 6-subiteration algorithms?in each iteration, they applied alternatively delete border voxels from six directions, upper, lower, north, south, east, west.
