Detection results of the CGAdaBoost classifier with FalseAlarmRate 0.03 and TruePositiveRate 0.9: (a) the detection result with single feature on the coronal view (a red circle for the undetected vertebrae and a green circle for the false detected vertebrae); (b) the detection result with multifeature on the coronal view; (c) the detection result with multifeature on the high-contrast coronal view; (d) the detection result with multifeature on the sagittal view.
