TL;DR: A support vector classifier approach was employed in predicting the risk of progression of adolescent idiopathic scoliosis (AIS), a condition that causes visible trunk asymmetries, and outperformed a "statistically equivalent" logistic regression model and a stepwise linear regression model on the said datasets.

Characterizing Torso Shape Deformity in Scoliosis Using Structured Splines Models
TL;DR: This paper describes a method of characterizing the torso shape deformity associated with scoliosis by both its type and severity, and assesses the accuracy and precision of this shape characterization scheme, and its relationship to the actual deformities present in the underlying spine.

Classifying torso deformity in scoliosis using orthogonal maps of the torso.
TL;DR: A technique for assessing torso shape and classifying scoliosis into mild, moderate and severe categories using two indices, ‘twist’ and ‘bend’, obtained from orthogonally transformed images of the complete torso surface called orthogonal maps is presented.

Validating an imaging and analysis system for assessing torso deformities
TL;DR: The numeric and functional validation of an imaging and analysis system used for assessing human torsos for deformities such as scoliosis shows that the system is robust to shape variations caused by sway and breathing and shows limited variability to the Cosmetic Score.

A Torso-Imaging System to Quantify the Deformity Associated With Scoliosis
TL;DR: Results of system calibration and error analysis show that the system can be used to quantify the deformity associated with scoliosis.
