Table 1.

Statistics (mean and standard deviation (STD)) of cartilage segmentation validation results. DSC is Dice similarity coefficient. SENS is sensitivity and SPEC is specificity. Note that we only segment the weight-bearing region of the femoral cartilage which makes the segmentation harder because of the smaller volume.
