CBCT images have been widely used in digital orthodontics. In images, there are some tooth boundaries of blurriness and disappearance, the teeth intensity inhomogeneity. order to identify these segment teeth, this paper develops an approach alternate level set evolutions with controlled switch via slice-by-slice segmentation: user selects a voxel inside initialize small circle encircling voxel,...

To accurately and efficiently complete tooth segmentation from a large amount of oral medical data, the burden doctors should be reduced. An automatic seed picking method based on 2D projection occlusal plane was proposed. First, authors establish two-dimensional data set for segmentation. Then, this article built prediction network teeth seeds YOLOv4 to realize position as well recognition cat...
