Facial recognition system introduced varying technologies to the procedure. Some of the most notable include the following techniques: Some face recognition algorithms identify facial features by extracting landmarks, or features, from an image of the subject's face. For example, an algorithm may analyze the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These features are then used to search for other images with matching features. Other algorithms normalize a gallery of face images and then compress the face data, only saving the data in the image that is useful for face recognition. A probe image is then compared with
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
