We are coding 14 features, organized as follows: 1: The right eyebrow of the face ;
2: The left eyebrow of the face;
3: The temporal corner of the right eye of the face;
4: The center of the right iris of the face;
5: The nasal corner of the right eye of the face;
6: The nasal corner of the left eye of the face;
7: The center of the left iris of the face;
8: The temporal corner of the left eye of the face;
9: The tip of the nose;
10:The right nostril of the face;
11:The left nostril of the face;
12:The tip of the upper front teeth;
13:The bottom of the right ear hole;
14:The bottom of the left ear hole.
Glasses: 3: Attachment of right spectacle arm to lens frame 5: Attachment of spectacle nose bar to right lens frame 6: Attachment of spectacle nose bar to left lens frame 8: Attachment of left spectacle arm to lens frame For consistency, if a particular subject has already been partially feature marked, each new coder should visually check the specific interpretation of features previously used for that subject. For example, the temporal corner of the glasses for subject 9 is rather large, and I labeled the truePoses several weeks before the labeling the AU's, without checking, resulting in a large vertical error on eye position.
Interlace Effects: Since many of the peak action units are blurred by the interlacing of 2 frames, it may be necessary to consciously choose the center of 2 possible feature points. What happens otherwise is that you naturally choose the frame with the strongest edge illusion, and that differs from point to point.
