Registered images belonging to user, otherwise not by treat carry out authentication user authentication.
Initial registration in the registered images set belonging to the registered images that the registered images determined are determined for this
During image, verification mode can be：Only by similarity maximum corresponding to the registered images determined and above-mentioned same similarity
Threshold value compares, then can be with when similarity maximum corresponding to the registered images determined is more than above-mentioned same similarity threshold
Pass through the authentication of the user to pending authentication.Otherwise do not tested by treating the identity for the user for carrying out authentication
Card.
In some optional implementations of the present embodiment, when the registered images determined are not the notes belonging to registered images
Volume image collection in initial registration image when, verification mode can be：The note belonging to the registered images determined can be calculated
The face object in initial registration image in volume image collection and the face pair in the image of the user of pending authentication
The similarity of elephant, the similarity can be referred to as initial registration image similarity.It is then possible to judge whether that satisfaction passes through bar
Part：Maximum similarity corresponding to the registered images that initial registration image similarity is more than the first similarity threshold and determined
More than the second similarity threshold, when meeting to pass through condition, determine that the user of pending authentication passes through authentication；When not
When satisfaction passes through condition, determine that the user of pending authentication does not pass through authentication.First similarity threshold can be less than
Second similarity threshold.
Initial registration figure in the registered images set that the registered images determined are belonging to the registered images determined
During picture, verification mode can be：Whether maximum similarity is more than the first similarity corresponding to the registered images for judging to determine
Threshold value.When similarity maximum corresponding to the registered images determined is more than the first similarity threshold, it may be determined that pending
The user of authentication passes through authentication.When similarity maximum corresponding to the registered images determined is less than the first similarity
During threshold value, determine that the user of pending authentication does not pass through authentication.
For example, the user of pending authentication is user A, it is assumed that comprising just in registered images set corresponding to user A
The user A of face object corresponding to beginning registered images and the face comprising user A subsequently registered in face identification system
Image.Initial registration image in registered images set corresponding to user A for user A utilize first face identification system to
Family A carries out the user A registered before authentication in face identification system image, i.e., utilizes face identification system pair first
Before user A carries out authentication, the image such as user A's for the user A being added in registered images set corresponding to user A
Certificate photo.The hour of log-on of initial registration image in registered images set corresponding to user A is in registered images corresponding to user A
In the hour of log-on of all registered images in set earliest.
Reach gate in user A, operate in after the image that face identification system on gate collects user A, from multiple
The registered images determined in registered images are the registered images in registered images set corresponding to user A.
When the image for the user A that the registered images determined are the newest registration in registered images set corresponding to user A
When, it is determined that the initial note in registered images set corresponding to the user A belonging to the image that the registered images gone out are not to determine out
Volume image, at this time, it may be necessary to meet the face of the user A in the initial registration image in registered images set corresponding to user A simultaneously
The similarity of the face object corresponding with the face of the user A in the user A collected image of face object corresponding to portion is big
User A in the user A of newest registration in registered images set corresponding to the first similarity threshold and user A image
Face corresponding to face object face object corresponding with the face of the user A in the user A collected image it is similar
When degree is more than the second similarity threshold, the authentication to user A could be passed through.
In other words, the time of the user A collected image is that can be used as current time, the user A used figure
As the user A image that uses of time in user A face corresponding to the feature of face object can represent current when
Between user A face feature.The newest user A registered in face identification system before user A image is collected
The feature of face object is newest in face identification system before can representing current time corresponding to the face of user A in image
The feature of the hour of log-on user A of the user A of middle registration image face.It is first in registered images set corresponding to user A
The feature of face object in beginning registered images can be expressed as the face of the time user A apart from current time certain time length
Feature.
Need to meet that the feature of current time user A face is used with the time apart from current time certain time length at the same time
The similarity of the feature of family A face be more than the feature of the first similarity threshold and current time user A face with it is newest
The similarity of the feature of the hour of log-on user A of the user A registered in face identification system image face is more than second
Similarity threshold, just pass through the authentication to user A.
When the registered images determined are the initial registration image in registered images set corresponding to user A, it is only necessary to
Meet face object corresponding to the face of the user A in initial registration image and the user A's in the user A collected image
The similarity of face object corresponding to face is more than the first similarity threshold, you can passes through the authentication to user A.
Assuming that user B reaches gate after the user A by authentication, it is not present in face identification system and belongs to use
Family B registered images.When carrying out authentication to user B, user B image is gathered first, it is assumed that the multiple notes determined
The phase of the face object face object corresponding with the face of the user B in the user B collected image included in volume image
Like the user A of the newest registration in the registered images set corresponding to user A of the maximum registered images of degree image, and determine
Maximum similarity corresponding to the registered images gone out is more than the second similarity threshold, i.e., in registered images set corresponding to user A
Newest registration user A image in user A face corresponding in face object and the user B image that collects
The similarity of face object corresponding to user B face is more than the second similarity threshold.
But because basis passes through condition, it is also necessary to by people corresponding to the face of the user B in the user B collected image
Face object corresponding to the face of the user A in initial registration image in the registered images set corresponding with user A of face object
Similarity and the first similarity threshold be compared.
Due to the registration corresponding with user A of face object corresponding to the face of the user B in the user B collected image
The similarity that the face of the user A in initial registration image in image collection corresponds to face object is less than the first similarity threshold
Value, therefore, user B can not pass through authentication.
In other words, the time of the user B collected image can be used as current time, the user B collected image
In user B face corresponding to face object feature can represent current time user B face feature.A couples of user
The feature of face object corresponding to the face of the user A in initial registration image in the registered images set answered can represent away from
The feature of face from the time user A of current time certain time length.
Feature and the face of the time user A apart from current time certain time length due to current time user B face
The similarity of feature be less than the first similarity threshold, can not meet by condition, then user B can not pass through authentication.
In some optional implementations of the present embodiment, pending authentication user by authentication it
Afterwards, the image of the user collected can be added to the registered images collection belonging to the registered images determined as registered images
In conjunction.So as to which the image of the user of the pending authentication collected be registered in face identification system.
For example, the user of pending authentication is user A, it is assumed that comprising just in registered images set corresponding to user A
The user A of face object corresponding to beginning registered images and the face comprising user A subsequently registered in face identification system
Image.Initial registration image is that user A knows before authentication is carried out to user A using face identification system first in face
The user A registered in other system image, i.e., before carrying out authentication to user A using face identification system first, add
To the image such as user A of the user A in registered images set corresponding to user A certificate photo.Registered images corresponding to user A
The registration of all registered images of the hour of log-on of initial registration image in set in registered images set corresponding to user A
In time earliest.
Reach gate in user A, operate in after the image that face identification system on gate collects user A, from multiple
The registered images determined in registered images are the registered images in registered images set corresponding to user A.
Assuming that the registered images determined are the image of the user A of newest registration in registered images set corresponding to user A
When, it is determined that the initial note in registered images set corresponding to the user A belonging to the image that the registered images gone out are not to determine out
Volume image, when the face of the user A in the initial registration image in registered images set corresponding to user A correspond to face object and
The similarity of face object corresponding to the face of user A in the user A collected image be more than the first similarity threshold with
And in face object corresponding to the face of the user A in the user A of newest registration image and the user A collected image
When the similarity of face object corresponding to user A face is more than the second similarity threshold, pass through the authentication to user A.
It is then possible to the user A collected image is added in registered images set corresponding to user A.
