The forensic comparisons of one facial image to one or more other facial images is known as Facial Mapping.
Three different approaches are used for facial mapping and these are photo-anthropometric, morphological and video superimposition.
- Photo-anthropometric comparison involves comparing measurements of distances and angles between facial landmarks measured on photographs. This is still a subjective method and measurements need to be interpreted and assessed with skill.
- Morphological comparison involved categorising facial features according to their type or shape and counting the number of similar categorisations across the comparison images. The method is subjective.
- Video superimposition involves overlaying one video image to on another another which of which has been scaled and rotated to provide the best match. This method can provide compelling graphics in courts but is still subjective as it requires skilful interpretation and assessment.
We undertake preliminary assessment for free. We offer a free initial consultation, agree the scope of the work to keep down costs, advise clients on progress, and produce jury friendly reports and give evidence in Court.
