Significance and Use4.1 Morphological analysis used for facial comparisonshould utilize consistent terminology and methodology. Thisguide provides a

9、 standard set of facial components,characteristics, and descriptors to be used as a framework inconjunction with a systematic method of analysis for facialimage comparison.4.2 The order of the facial components in this set ispresented from the top of the face to the bottom, not in orderof importance

10、 or priority.4.3 Within this guide, the term “face” generally refers to theface, head, and neck inclusively unless specified otherwise.4.4 There are several instances in this guide in which theterm “distance” or “approximate distance” is used. When thisterm is used in this guide, it does not mean to

11、 imply that theprecise value of this dimension shall be determined, but ratherthe relative size of this dimension compared to the overallwidth or height of the face, if not otherwise specified. In thisguide, it is recommended that photoanthropometry not be usedat all because of its limitations.5. Fa

The tables in 5.3 furtherexpands each facial component into

16、ions issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15.3 Facial ComponentsThe human facial components aremultifaceted and when imaging conditions allow, it may bepossible to subdivide these components further. Any standardprocedure using facial comparison analysis

17、 should consider allof the following facial components: Skin, Face/Head Outline,Face/Head Composition, Hair, Forehead, Eyebrows, Eyes,Cheeks, Nose, Ears, Mouth, Chin/Jawline, Neck, Facial Hair,Facial Lines, Scars, Facial Marks, and Alterations. If featuresare present and observable on a face that ca

18、nnot fit into thecategories below, those features should be considered andincluded as part of 5.3.19.5.3.1 Skin“Skin” refers to the overall appearance of theskin.
