Claim 2:
3. The computerized method of claim 2, wherein detecting the asymmetric change in position of at least one reference point of a plurality of reference points comprises:
defining an initial position for the plurality of reference points that correspond to one or more additional anatomical features on the face of the person relative to the x-axis, the y-axis, and the z-axis using at least a portion of the image data;
tracking the plurality of reference points in the image data;
computing changes in position of the plurality of reference points relative to the at least one axis of the 3-dimensional (3D) axis system; and
determining that the asymmetric change in the position of the at least one reference point is consistent with a stroke symptom based on a computed change in position of the at least one reference point is maintained for a minimum number of images included in the image data.
