And then according to the feature of the shape, determine the facial size of N number of human face region.For example, after recognition of face, the face of acquisition
Region can be rectangle, and the feature such as the area of the rectangle, width may be incorporated for characterizing the size of human face region.In practical application
In, the factor such as the hair style of personage, headwear, cap may interfere with the accuracy judged human face region length.It is therefore preferable that
, can be using the width of human face region as the feature for weighing human face region size.
Specifically, the profile coordinate can be a coordinate in rectangular coordinate system, wherein, ordinate value is identical,
And two profile coordinates of abscissa difference maximum absolute value, it can be used for the width for weighing the human face region.If with face area
The width in domain characterizes the absolute value of the size, the then difference of two profile coordinate abscissas of human face region, can be used as the people
The size in face region.
Step 203, main body human face region and nonbody human face region are determined from N number of human face region.
Specifically, main body human face region can be determined first from N number of human face region, table is needed with the prominent view data
Existing emphasis, nonbody human face region is determined by the main body human face region.And using the main body human face region as to each non-
The benchmark of main body human face region virtualization.
It is determined that during main body human face region, can be chosen by selection rule set in advance from each human face region
Go out main body human face region.For example, when being imaged to more people, often the people nearer from camera is more to need emphasis to embody
, and according to Perspective Principles, the size for being usually located at people's corresponding human face region in view data of foremost is maximum.Cause
This, can choose the maximum human face region of size in N number of human face region, as main body human face region, and by the view data
In other human face regions as nonbody human face region.As another embodiment, user can also be received in the picture
First input, and human face region corresponding to first input is defined as main body human face region.For example, what can be will identify that is every
Individual human face region shows user on display interface, and after the human face region of user's selection is received, the user is selected
Human face region is as main body human face region, and using other human face regions in the view data as nonbody human face region.So as to
Fully meet the needs of user independently selects, enhance operability and practicality.In actual applications, user can be by touching
The mode such as control or acoustic control selects one in N number of human face region to be used as main body human face region.For another example, can be by N number of face area
Line label is entered in domain according to order from left to right, and shows user.User can select a certain face by selecting label
Region is as main body human face region.And by each face area in N number of human face region in addition to human face region corresponding to the label
Domain is identified as nonbody human face region.
Step 204, it is determined that each nonbody human face region and the absolute value of the facial size difference of main body human face region.
, can be to determine Subject-Human it is determined that after main body human face region and nonbody human face region in N number of human face region
Face region and the facial size of each nonbody human face region, and the people of each nonbody human face region and main body human face region
The absolute value of face dimension difference.
Specifically, it can be characterized every according to the ratio of each nonbody human face region width and main body face peak width
The facial size difference of individual nonbody human face region and main body human face region.For example, it can first calculate each nonbody face area
Domain and the ratio a of main body face peak width.Pass through the absolute value of ratio a and 1 difference | 1-a | * X, weigh each non-master
The how far of body human face region and main body human face region, and then it is determined for the virtualization to each nonbody human face region
Degree.For example, if not the width ratio of main body human face region A and main body human face region is 0.8, then nonbody human face region A with
The absolute value of the facial size difference of main body human face region is 0.2.If not main body human face region B and main body human face region width
Ratio is 1.3, then nonbody human face region B and the absolute value of the facial size difference of main body human face region are 0.3.
Step 205, according to the absolute value of facial size difference, different virtualization degree are carried out to nonbody human face region respectively
Virtualization processing.
Specifically, when being blurred to view data, it will usually which the background area in view data is blurred.And
And in actual applications, because the view data of single camera shooting lacks depth of view information, therefore, to background in view data
The unified virtualization degree of region generally use.
, can be according to the absolute value of the facial size difference and to the background it is determined that after virtualization degree to background area
The virtualization degree in region, it is determined that the virtualization degree of each nonbody human face region.According still further to the void of each nonbody human face region
Change degree, virtualization processing is carried out to each nonbody human face region respectively.Wherein, background area be image in except human face region it
Outer all image-regions, the absolute value positive of the virtualization degree of each nonbody human face region and corresponding facial size difference
Close.
For example, if the virtualization degree to background area is X, the facial size of nonbody human face region and main body human face region
The absolute value of difference is m, then the virtualization degree to nonbody human face region can be mX.And according to the virtualization degree to nonbody
Human face region carries out virtualization processing.When more than two nonbody human face region in view data being present, and each nonbody face
During the absolute value difference of facial size difference corresponding to region, each nonbody human face region will be entered with different virtualization degree
Row virtualization is handled, so as to embody the distance difference of each personage in scene corresponding to view data.Wherein, to nonbody face area
The virtualization degree in domain and the absolute value of the facial size difference are into positive correlation.In actual applications, it is not limited to above-mentioned ratio approach.
In summary, in embodiments of the present invention, by obtaining N number of human face region in view data in same plane
Profile coordinate, distinguish the front and back position relation of each human face region in view data so that this method can lack depth of field letter
In the case of breath, remain to carry out virtualization processing to human face region in view data respectively with different virtualization degree, not only effectively
