Description
Technical field
The utility model relates to technical fields such as Digital Image Processing, pattern-recognition and wireless telecommunications, portable terminal such as particularly a kind of mobile phone with facial image recognition function, PDA.
Background technology
Recognition of face has been used for authentication.Recognition of face is compared with other recognition technologies, has nature, easy, easy-to-use, numerous advantages such as user's acceptance good, noncontact, non-invasion.Therefore, face recognition technology can be widely used in safety verification, monitoring, gateway control, computer login, internet login and authentication, electronic commerce information system, national treasury safety installations, safety cabinet, ATM (Automatic Teller Machine), chase suspect, anti-terrorism struggle and other fields that is suitable for.
Fig. 1 shows the face recognition process of prior art, is people's face in facial image to be identified and the database is compared, and makes the identification judgement then.Comparison identification is to carry out on the basis of face characteristic sign indicating number.This process is compared 30 3 steps by image acquisition 10, feature extraction 20 and feature templates and is finished.Then comprise corresponding to face identification system: image capture module, facial image or image/video sequence that it is gathered by image collecting device (as video camera, digital camera etc.) then, are delivered to computing machine with these images or video sequence and are handled; Characteristic extracting module, it is arranged among the computing machine, detection and location people face part from the image of input, and extract the characteristic information of people's face after human face posture is proofreaied and correct, i.e. face characteristic sign indicating number; The feature templates comparing module, be arranged among the computing machine equally, it compares the characteristic information (face characteristic sign indicating number) that is deposited in people's to be identified face characteristic information (face characteristic sign indicating number) and the face characteristic database, and finds out best match objects in these information.
Obviously, the face characteristic database need be set up before identification.Therefore, face identification system should have by recognition of face A and the typing of the people's face B two big processes of filing and constitutes, referring to Fig. 2.Wherein, the file purpose of B process of people's face typing is to be based upon the face characteristic database that uses in the face recognition process.
Recognition of face A and the typing of the people's face B two big processes of filing include image acquisition and characteristic extraction procedure, to obtain image and to extract feature.But face recognition process is the condition code that will extract and the condition code that the face characteristic database is deposited in carries out feature templates comparison coupling, and people's face typing create procedure then deposits the condition code of extraction in the face characteristic database.
The feature extraction 20 of people's face is detected by people's face or the feature location of face tracking 201, people's face with proofread and correct 202, face characteristic extracts several steps such as 203 and constitutes.The detection of people's face is meant in dynamic scene and complicated background and catches people's face and isolate people's face, face tracking refers to the people's face that is detected is carried out dynamic target tracking, people's face is proofreaied and correct and is utilized key position that people's face is carried out geometry correction (as proofreading and correct the human face posture of skew), and face characteristic extracts 203 pairs of people's faces that detect after proofreading and correct and calculates the essential characteristic that extracts face.
30 of the feature of people's face contrasts are based on to be extracted face characteristic will the people's face in the face characteristic database 40 to be identified to carry out matching ratio right, calculates matching confidence, and adjudicates the optimum matching object.Matching ratio is to being (identity validation) or one-to-many (identification) one to one.
(PDA, or individual palm PC) is more and more universal for the mobile terminal device of present embedded camera such as mobile phone and personal digital assistant, and they self mobile computing and memory function is also more and more stronger, and corresponding wireless application software is also flourish.
