Specific embodiment
Hereinafter, certain exemplary embodiments are simply just described.As one skilled in the art will recognize that
Like that, without departing from the spirit or scope of the present invention, described embodiment can be modified by various different modes.
Therefore, attached drawing and description are considered essentially illustrative rather than restrictive.
The embodiment of the invention provides a kind of lookup target person methods, as shown in Figure 1, comprising the following steps:
S100: the face-image of collected target person is identified.Wherein, collected face-image can be multiple,
I.e. respectively by different acquisition equipment in different time place acquired image.
S200: the facial feature data in the face-image of target person is extracted.Facial feature data is for characterizing target
The face information of personage can find image (photo or view with the target person according to the facial feature data extracted
Frequently).
S300: according to facial feature data, at least one crucial group photo is obtained from picture database；Wherein, crucial to close
The face-image of face-image and other personages according in including target person, and two people are included at least in crucial group photo
Object.The database that arbitrary source in the prior art provides can be used in picture database.It may include more people in picture database
Group photo and single photograph.Preferably, the picture database only with more people group photo can be used, to improve the effect for screening crucial group photo
Rate.
S400: according to the face-image of other personages in crucial group photo, it is screened out from it at least one association personage.
S500: the relevant information of the information searching target person of association personage is utilized.It is to be understood that will be associated with personage's
Some information find more relevant informations related with target person by clue as clue.It is also understood that root
According to the personal information of association personage, association personage is found, obtains more related letters in relation to target person by being associated with personage
Breath.To increase the probability for finding target person.
In one embodiment, when the face-image of the target person of acquisition is multiple, each face-image can be carried out
The face-image use that can wherein extract most facial characteristics is chosen in selection.Or each face-image is extracted respectively
Facial feature data, and each facial feature data is polymerize, form the face for more accurately characterizing target person face information
Characteristic.
In one embodiment, as shown in Fig. 2, according to facial feature data, at least one is obtained from picture database
Zhang Guanjian group photo, comprising:
S310: filtering out group photo set from picture database, includes several group photos in group photo set, every in group photo
A personage all has default facial feature data.Wherein, in the group photo set for establishing picture database, to each of deposit
The face of each personage in group photo identifies, and the corresponding facial feature data of the face for extracting each personage is as default
Facial feature data, and be associated in group photo.
S320: by the facial feature data of target person and it is each group photo each of object default facial feature data into
Row matching.If successful match, the group photo of successful match is filtered out and is taken a group photo as key.It filters out with target person
Group photo can be used as crucial group photo.
It should be noted that if when the key group photo with target person filtered out is excessive, it can be by some customized
Rule screens each crucial group photo, selects the crucial group photo for being more in line with requirement.For example, custom rule is group photo shooting
Time, place, character relation etc. is used as screening index in group photo.
In one embodiment, as shown in figure 3, therefrom being sieved according to the face-image of other personages in crucial group photo
Select at least one association personage, comprising:
S410: the face-image of other each personages in the crucial group photo of identification.
S420: facial images match will respectively be prestored in the face-image and facial database of other each personages；If matching
Success then filters out other personages of successful match as association personage.Wherein, face-image is respectively prestored in facial database
Relevant information containing corresponding personage.Due to each personage in crucial group photo can not necessarily find it is corresponding
Personal information, it is therefore desirable to be screened by facial database.
In one embodiment, as shown in figure 4, when key group photo is multiple, according to other people in crucial group photo
The face-image of object is screened out from it at least one association personage, comprising:
S430: the face-image of other each personages in each crucial group photo of identification.
S440: the face-image of every other personage is polymerize, and obtain frequency of occurrence be higher than threshold value other people
Object is as association personage.The i.e. same personage occurs in multiple key group photos with target person, it may be considered that the people
Object possibility associated with target person is bigger.By frequency of occurrence, more main pass can be quickly and effectively filtered out
Join personage, to increase a possibility that finding the relevant information of target person.
