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
