(1) Face datection
Looks detection, which refers to, judges whether there is image surface in dynamic scene and complicated background, and isolates this image surface.
Generally there is following several method:
1. reference template method
The template of one or several standard faces is designed first, then calculates between the sample and standard form of test acquisition
With degree, and pass through threshold value to determine whether there are faces；
2. face rule method
Since face has certain structure distribution feature, the method for so-called face rule is extracted these features and is generated accordingly
Rule is to judge whether test sample includes face；
3. sample learning method
This method is the method for using artificial neural network in pattern-recognition, i.e., by opposite as sample sets and the decent product of non-face
The study of collection generates classifier；
4. complexion model method
This method is to be distributed the rule of Relatively centralized in color space according to the looks colour of skin to be detected.
5. sub-face of feature method
This method be all image surface set are considered as to an image surface subspace, and based on test sample and its subspace throwing
The distance between shadow judges whether there is image surface.
It is worth mentioning that above-mentioned 5 kinds of methods can also integrate use in actually detected system.
(2) face tracking
Looks tracking, which refers to, carries out dynamic target tracking to the looks being detected.The specific method used based on model is based on
Move the method combined with model.In addition, tracking a kind of simple and effective means of also can yet be regarded as using complexion model.
(3) face alignment

That is the image surface sampled is successively compared with the image surface of inventory, and find out optimal matching object.So image surface
Description determine the specific method and performance of face recognizing.Mainly using feature vector and two kinds of description methods of face line template:
1. feature vector method
This method is first attributes such as size, position, distance of the image surfaces such as determining eye iris, the wing of nose, corners of the mouth face profile, then again
Their geometric feature is calculated, and these characteristic quantities form a feature vector for describing the image surface.
2. face line template
This method is to store several standard image surface templates or image surface organ template in library to sample image surface when being compared
All pixels are matched with templates all in library using normalization correlative measurement.In addition, also using oneself of pattern-recognition
The method that network of relation or feature are combined with template.
The practical core of face recognition technology is " partial body's signature analysis " and " figure/nerve recognizer." this
Algorithm is the method using each organ of human body face and characteristic portion.Geometrical relationship majority is such as corresponded to according to formation identification parameter and number
It is compared, judges and confirmation according to initial parameter all in library.It is general to require to judge the time lower than 1 second.

Facial image pretreatment: the image preprocessing for face is based on Face datection as a result, handling image
And finally serve the process of feature extraction.The original image that system obtains by various conditions due to being limited and being done at random
It disturbs, tends not to directly use, it is necessary to which it is pre- to carry out the images such as gray correction, noise filtering to it in the early stage of image procossing
Processing.For facial image, preprocessing process mainly includes light compensation, the greyscale transformation, histogram of facial image
Equalization, normalization, geometric correction, filtering and sharpening etc..
Facial image feature extraction: it is special that feature workable for face identification system is generally divided into visual signature, pixels statistics
Sign, facial image transformation coefficient feature, facial image algebraic characteristic etc..Face characteristic extracts certain spies aiming at face
What sign carried out.Face characteristic extracts, and also referred to as face characterizes, it is the process that feature modeling is carried out to face.Face characteristic extracts
Method be summed up and be divided into two major classes: one is Knowledge based engineering characterizing methods；Another is based on algebraic characteristic or system
Count the characterizing method of study.
Knowledge based engineering characterizing method mainly according to the shape description of human face and they the distance between characteristic
The characteristic for facilitating face classification is obtained, characteristic component generally includes Euclidean distance, curvature and angle between characteristic point
Degree etc..Face is locally made of eyes, nose, mouth, chin etc., and to these parts and the geometry of structural relation is retouched between them
It states, can be used as the important feature of identification face, these features are referred to as geometrical characteristic.The main packet of Knowledge based engineering face characterization
Include method and template matching method based on geometrical characteristic.
Facial image matching and identification: the feature templates stored in the characteristic and database of the facial image of extraction into
Row search matching, by setting a threshold value, when similarity is more than this threshold value, then result matching obtained is exported.Face
Identification is exactly to be compared face characteristic to be identified with obtained skin detection, according to similarity degree to face
Identity information is judged.This process is divided into two classes again: one kind is confirmation, is the one-to-one process for carrying out image comparison, separately
One kind is identification, is the one-to-many process for carrying out images match comparison.
Specifically, the face recognition module includes two kinds of comparison modes of verification formula and search type, verification formula is will to finger
Capture that registered in obtained portrait or specified portrait and database certain is a pair of as the verification that compares determines whether it is
The comparison of same people, search type refer to that search searches whether specified portrait from all portraits registered in database
In the presence of.
