From: The segmentation of bones in pelvic CT images based on extraction of key frames
Example results of Patient 1 obtained by the watershed algorithm based on skeleton markers. (a) is the input image as well as the pre-processed image. (b) is the skeleton image the for foreground and indicates the location of the pelvic structure. (c) is the skeleton image for the background and indicates the location of the other structures. (d) is the segmentation result and it is shown in the pre-processed image. The automatically segmented pelvic structure contours are displayed in red
