Firstly, the key frames were extracted from the video sequence. Then, the features detected between adjacent key frames were guided and matched by motion displacement, which was calculated by the optical flow field. With the RANSAC robust estimation and cascade of homography matrix, the homography matrix of the adjacent key frame and the nonadjacent key frame was got. Finally, the seamless mosaic was rendered by image blending.

Our results showed that the most appropriate rib's level for applying force was below the apex of scoliotic spine. From this appropriate level, the stress delivered to its conjunctive vertebra was the highest, as 1.3~1.8 times compared with others. Furthermore, the correction of Cobb's angle was also the highest, achieved 15%. The ML force was dominant in alteration of Cobb's angle, whereas the AP force was dominant in alteration of axial vertebral rotation. In addition, initial vertebral rotation influenced neither correction nor stress.
