Image Based Regression

CREATED: 200701070553 ** Body segment parameters

• center of mass
• mass
• moment of inertia

** Regression equations

• based on cadaver studies
• assume girth is elliptical

** Image based techniques

• X-ray, CT scan
• calculate mass along each pixel
• DEXA - duel energy X-ray densitometry ** high radiation, limited avilability of machines

** Image based regression

• feature based image warping to predict DEXA image of new subject
