Face Recognition Systems: A Survey

Over the past few decades, interest in theories and algorithms for face recognition has been growing rapidly. Video surveillance, criminal identification, building access control, and unmanned and autonomous vehicles are just a few examples of concrete applications that are gaining attraction among industries. Various techniques are being developed including local, holistic, and hybrid approaches, which provide a face image description using only a few face image features or the whole facial features. The main contribution of this survey is to review some well-known techniques for each approach and to give the taxonomy of their categories. In the paper, a detailed comparison between these techniques is exposed by listing the advantages and the disadvantages of their schemes in terms of robustness, accuracy, complexity, and discrimination. One interesting feature mentioned in the paper is about the database used for face recognition. An overview of the most commonly used databases, including those of supervised and unsupervised learning, is given.

Metrics details. It inherits advantages from traditional 2D face recognition, such as the natural recognition process and a wide range of applications. Moreover, 3D face recognition systems could accurately recognize human faces even under dim lights and with variant facial positions and expressions, in such conditions 2D face recognition systems would have immense difficulty to operate.

In recent years, 3D face recognition has attracted increasing attention from worldwide researchers. Rather than homogeneous face data, more and more applications require flexible input face data nowadays. Adding the Laplacian penalty constrain for the multiview feature learning, the proposed MSDA is first proposed to extract the cross-modality 2D-3D face features. The MSDA aims at finding a multiview learning based common discriminative feature space and it can then fully utilize the underlying relationship of features from different views. To speed up the learning phase of the classifier, the recent popular algorithm named Extreme Learning Machine ELM is adopted to train the single hidden layer feedforward neural networks SLFNs.

Many researches in face recognition have been dealing with the challenge of the great variability in head pose, lighting intensity and direction,facial expression, and aging. The main purpose of this overview is to describe the recent 3D face recognition algorithms. The last few years more and more 2D face recognition algorithms are improved and tested on less than perfect images. However, 3D models hold more information of the face, like surface information, that can be used for face recognition or subject discrimination. Another major advantage is that 3D face recognition is pose invariant.

 - Я гожусь тебе в матери. Могла бы не напоминать, - подумал. Мидж подошла к его столу. - Я ухожу, но директору эти цифры нужны к его возвращению из Южной Америки. То есть к понедельнику, с самого утра.

Один из прямоугольников вдруг закрыла чья-то тень. Даже не взглянув на верхушку башни, Халохот бросился к лестнице. ГЛАВА 99 Фонтейн время от времени стучал кулаком по ладони другой руки, мерил шагами комнату для заседаний, то и дело посматривая на вращающиеся огни шифровалки. - Отключить. Черт побери, немедленно отключить. Мидж появилась в дверях со свежей распечаткой в руке. - Директор, Стратмору не удается отключить ТРАНСТЕКСТ.

 Черт! - Фонтейн снова схватил трубку и набрал номер мобильника Стратмора. На этот раз послышались длинные гудки. Фонтейн насчитал уже шесть гудков. Бринкерхофф и Мидж смотрели, как он нервно шагает по комнате, волоча за собой телефонный провод. Директор АНБ напоминал тигра на привязи. Лицо его все сильнее заливалось краской.
