IMAGE SEGMENTATION APPARATUS, MEDICAL IMAGE DEVICE AND IMAGE
SEGMENTATION METHOD |
| 摘要 |
The disclosure provides an image segmentation apparatus, an image segmentation method and a medical image device for segmenting an object having a tree-shaped tubular structure from a volume image consisting of a series of images photographed on the basis of slices. The image segmentation apparatus comprises: a self-adaptive region growing unit configured to perform region growing according to the volume image, based on a seed point and a preset threshold to obtain at least one part of the tree-shaped tubular structure; and a growing control unit configured to change the preset threshold to re-perform the region growing until a given condition is met. |
