Method and apparatus for orienting image representative data

摘要

A method for processing a three-dimensional image file captured directly from a live subject, the file including the cranium of the subject, comprises: providing a vertex point cloud for the three-dimensional image file; determining a median point for the vertex point cloud; determining a point on the cranium; and utilizing the median point and the cranium point to define a z-axis for the three-dimensional image file.

1. A method for processing a three-dimensional image file acquired directly from a live subject, comprising:
determining a z-axis for said three-dimensional image file: determining a Frobenius norm for said three-dimensional image file; and utilizing Frobenius scaling on said three-dimensional image file to generate a scaled three-dimensional image file; orienting said scaled three-dimensional image file to a reference three-dimensional image file oriented to a reference z-axis, said reference three-dimensional image file being determined from a database comprising a plurality of three-dimensional image files each acquired directly from a corresponding plurality of live subjects and each oriented to said reference z-axis to produce an oriented three-dimensional image file; and processing said oriented three-dimensional image file to produce a cropped three-dimensional image file.
