Forensic facial reconstruction accurate reconstruction possible is largely limited. A second problem is the lack of a methodological standardization in approximating facial features. A single, official method for reconstructing the face has yet to be recognized. This also presents major setback in facial approximation because facial features like the eyes and nose and individuating characteristics like hairstyle - the features most likely to be recalled by witnesses - lack a standard way of being reconstructed. Recent research on computer-assisted methods, which take advantage of digital image processing, pattern recognition, promises to overcome current limitations in facial reconstruction and linkage. Reconstructions only reveal the
Facial width to height ratio Facial width to height ratio Facial width to height ratio (fWHR) is a measure derived from archaeological skull measurements. fWHR is not linked with adolescent testosterone, and has been proposed as: a predictor of aggression, cause of death by violence, and also with CEO success probability. While most studies have found some significance some have found little correlation. fWHR has also been used in primate studies with similar findings. Width is measured as upper bizygomatic width (the widest central bit of the face), height measurement used is upper facial height, from the top of the eyelids (approximately the nasion) to
