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 toning muscle exercising. There are two types of facial toning exercises: active and passive face exercises. Face exercises involves repeated voluntary contractions of certain facial muscle groups. The effectiveness of these facial toning techniques in improving appearance is scientifically unproven. Passive exercising by direct skeletal muscle electrostimulation. In this, flat metal electrodes with a conductive gel are affixed to certain points in the face and electrostimulation causes facial muscle contractions. Facial toning Facial toning, or facial exercise is a type of cosmetic procedure or physical therapy tool which promises to alter facial contours by means of increasing muscle tone, and facial
