图3 不同方法在5个示例上的分割结果和相应的人工标注 Note： Five samples, designated from A to E, were randomly selected from the test set data of cervical vertebra segmentation images. The cervical vertebra segmentation method based on the Transformer and diffusion model was compared with the original input image, two additional methods (U-Net and SOLOv2), and the ground truth. The regions delineated by the dashed circles represent the areas where the segmentation results of the various methods differ from the ground truth.
