Superimposition Techniques in Forensics

The video tutorial explains the superimposition technique used to identify if a skull belongs to a person in a photograph. It covers the types of superimposition methods, including photographic, video, and computer-assisted techniques. The procedure involves enlarging the photograph, preparing negatives, and aligning them with the skull's negative. Key precautions include ensuring a complete skull and considering facial tissue thickness. The technique's medico-legal importance is highlighted, noting its role in confirming identity, though acknowledging more advanced methods exist today.
