Figure 5From: Automated ventricular systems segmentation in brain CT images by combining low-level segmentation and high-level template matchingComparison of different symmetric measurements. (a) This result uses the difference between thicknesses on each side of the skull to measure symmetry. (b) This result uses the difference between center-to-edge distances on each side. Because of the irregularity on the skull edge, the thickness based symmetry cost sometimes leads to wrong approximate position.Back to article page
