Bal algorithm in [7]Prefilterig step , the scaling factor is set to 10,
the relationship between width and length of Gaussian filter is set to 2 .
Segmentation stepK-means segmentation using 5 classes with CT values: −950 (air),
0 (soft tissue), 200 (normal tissue), 750 (bone), 5000 (metal).
Inpainting stepLinear interpolation using 5 points in each symmetric side
