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 implant Facial implant Facial implants are used to enhance certain features of the face. The surgery may be elective, or needed as the result of prior surgery on the face. Each involves placing synthetic materials deep under the subcutaneous tissue and onto the underlying bone. A maxillofacial or plastic surgeon uses them to aesthetically improve facial contours, proportion and correct imbalances caused by injury or hereditary traits. However, in cases that require orthognathic osteotomies, those should be done before any implants are considered. In most cases, facial implant surgery is completed on an outpatient basis in a hospital, a surgeon's office
