In video superimposition for forensic identification, the technique is used to compare a skull with a photograph of a missing person. A true match requires:

• A Exact concordance of at least 12 dental features between the skull and the photograph
• B Correspondence of skull morphological landmarks (glabella, nasion, zygion, gnathion) with facial landmarks in the photograph on calibrated scaling ✓
• C DNA extraction from the skull for comparison with living relatives; visual superimposition alone is insufficient
• D Matching of the skull's capacious dimensions with anthropometric data from the victim's medical records

Explanation

Photographic or video superimposition is a technique of positive identification where the skull is superimposed over a life photograph of the suspected individual using calibrated scaling and landmark correspondence. Key craniofacial landmarks used include glabella, nasion, supraorbital margins, zygomatic arches, nasal tip, chin (gnathion), dental arch, and orbital contours. For a match to be accepted, multiple bony landmarks must align consistently. Superimposition was notably used in the identification of the skulls of Hitler and Mengele. DNA is the gold standard but superimposition is admissible when DNA is unavailable.
