3D model of a human face. Three-dimensional face recognition (3D face recognition) is a modality of facial recognition methods in which the three-dimensional geometry of the human face is used. It has been shown that 3D face recognition methods can achieve significantly higher accuracy than their 2D counterparts, rivaling fingerprint recognition.
Face hallucination algorithms that are applied to images prior to those images being submitted to the facial recognition system use example-based machine learning with pixel substitution or nearest neighbour distribution indexes that may also incorporate demographic and age related facial characteristics. Use of face hallucination techniques ...
This algorithm is very slow but better ones have been proposed such as the project out inverse compositional (POIC) algorithm and the simultaneous inverse compositional (SIC) algorithm. [5] Learning-based fitting methods use machine learning techniques to predict the facial coefficients.
Medioni has also worked on face modeling and introduced a technique for building human face models by using only two photographs. [23] Through collaborative research efforts he proposed a 3D face modeling and recognition system [ 24 ] and a method to produce 3D face models in laser scan quality. [ 25 ]
The algorithms for solving this problem are specialized for locating a single pre-identified object, and can be contrasted with algorithms which operate on general classes of objects, such as face recognition systems or 3D generic object recognition. Due to the low cost and ease of acquiring photographs, a significant amount of research has ...
FaceNet is a facial recognition system developed by Florian Schroff, Dmitry Kalenichenko and James Philbina, a group of researchers affiliated with Google.The system was first presented at the 2015 IEEE Conference on Computer Vision and Pattern Recognition. [1]
A face shape of vertices is defined as the vector containing the 3D coordinates of the vertices in a specified order, that is . A shape space is regarded as a d {\textstyle d} -dimensional space that generates plausible 3D faces by performing a lower-dimensional ( d ≪ n {\textstyle d\ll n} ) parametrization of the database.

The Viola–Jones object detection framework is a machine learning object detection framework proposed in 2001 by Paul Viola and Michael Jones. [1] [2] It was motivated primarily by the problem of face detection, although it can be adapted to the detection of other object classes. In short, it consists of a sequence of classifiers.
