1. A method for detecting facial motion of at least a portion of an individual'"'"'s face comprising:
- producing a digitized frame of the individual'"'"'s face in a reference position of the individual'"'"'s face, identified as a digitized control frame;
producing a digitized frame of the individual'"'"'s face in a moved position of the individual'"'"'s face, different from the position of the individual'"'"'s face in the reference position, identified as a digitized changed frame, where the moved position is produced substantially by facial musculature movements of the individual; and
comparing the digitized control frame with the digitized changed frame and determining shape changes over a defined surface area of the the individual'"'"'s face from the reference position to the moved postion.

Abstract
A method for detecting and quantifying motion of a body part of an individual or animal, such as an individual'"'"'s face or portion thereof. A digitized image of the body part in a reference position is produced (referenced image). A digitized image of the body part in a changed position then is produced (changed image). The referenced image is compared with the changed image to determine movement parameters indicating the movement of the body part from the referenced image to the changed image.

13. A method for detecting and quantifying facial motion of at least a portion of an individual'"'"'s face comprising:
-
producing a plurality of digitized frames of the individual'"'"'s face as the individual'"'"'s face is moved from one position to another position as a result substantially of facial musculature movements of the individual and designating one of the digitized frames as a digitized control frame and the remaining digitized frames as digitized changed frames; and comparing each digitized changed frame with the digitized control frame to determine the shape changes over a defined surface area for each comparison, with each of the determined shape changes over the defined surface area being indicative of shape changes over the defined surface area of the individual'"'"'s face between the digitized changed frame compared with the digitized control frame. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method for detecting facial motion of an individual'"'"'s face comprising:
-
producing a digitized frame of the individual'"'"'s face in a referenced position of the individual'"'"'s face, identified as a digitized control frame; producing a digitized frame of the individual'"'"'s face in a moved position of the individual'"'"'s face identified as a digitized changed frame wherein the moved position is produced substantially by facial musculature movements of the individual; and comparing the digitized control frame with the digitized changed frame to determine shape changes over a defined surface area of the individual'"'"'s face from the control position to the changed position. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for detecting facial motion of an individual'"'"'s face comprising:
-
performing via the individual at least one of the following movements;
(1) raising eyebrows from a rest position to a raised position, (2) smiling from a rest position to a smiled position, (3) closing the eyes from a rest position to a fully closed position of the eyes and (4) wrinkling the nose from a rest position to a fully wrinkled position;producing a digitized frame of the individual'"'"'s face in a control position wherein the individual'"'"'s face is at rest, identified as a digitized control frame; producing a digitized frame of the individual'"'"'s face when the individual'"'"'s face is positioned in at least one of the following moved positions;
(1) raised eyebrows, (2) smiling, (3) eyes closed, and (4) wrinkled nose and identifying that digitized frame as a digitized changed frame where the moved positions are produced substantially by facial musculature movements of the individual; andcomparing the digitized control frame with the digitized changed frame to determine shape changes over a defined surface area of the individual'"'"'s face from the control position to the changed position. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A method for detecting facial movements of an individual'"'"'s face comprising:
