1. A method for automated landmark extraction from three-dimensional whole body scanned data, the method comprising:

  • using a computer to perform the steps of;

    extracting feature points as landmarks on the human body;

    directly extracting intersection of neck and shoulder, acromion, chest line, hip line, and rearmost of hip based on three-dimensional changes in shape of the body without premarking landmarks prior to scanning;

    utilizing silhouette analysis by projecting the three-dimensional whole body scanned data onto a coronal plane to extract an intersection of the neck and shoulder by locating locally minimum points on silhouette curves; and

    extracting the intersection of the neck and shoulder at a point between a neck top and the acromion with a maximum vertical distance to a line connected by the neck top and the acromion.
