From: The segmentation of bones in pelvic CT images based on extraction of key frames
Example results using the watershed algorithm based on skeleton markers and the GVF model. These testing images are from Patient 1. (a) is the input image as well as the pre-processed image. (b) is the manual segmentation results of the corresponding key frame, and the edges are shown in green. (c) is the automatic segmentation results of the watershed algorithm based on skeleton markers, and the edges are shown in red. (d) is the segmentation results of the GVF model, the edges are shown in red and they are shown in the pre-processed image
