a, c the deviation patches of two torsos analyzed by Komeili et al. [12], in which the 3 mm deviation was defined as the threshold between normal and deformed area, and b, d the deviation patches of the same torsos analyzed by the modified ST analysis proposed in this study with the threshold of 9.33 mm. The arrows point to the artifacts in deviation patches, such as continuous deviation patches on the back and side of the torso and deviation patches due to the folded skin near the armpits, which were resolved after using the suggested modifications in this study. The green regions of the torso are considered normal. The blue and red patches represent abnormal protruded and indented regions of the torso, respectively, due to the scoliosis condition
