In a kind of inter-vehicle information system theme selection method of above-described embodiment and device, by user's face image
Match cognization is carried out with the standard face image, comprising:
The face image is divided into multiple subgraphs, the face image is calculated according to the noise spot quantity of subgraph
Noise level:
In formula, δ (max) is the noise spot quantity for the subgraph that noise spot quantity is most in each subgraph, δi(max) for
The noise spot quantity of i-th neighbouring of subgraph of the most subgraph of noise spot quantity, nmaxFor the son most with noise spot quantity
The neighbouring number of sub-images of image, δ (T) are preset noise spot amount threshold；
As G > 1, the face image is filtered.
Wherein, the filtering processing can be mean filter processing or gaussian filtering process.
The present embodiment innovatively proposes the measurement index of noise level, determines user's face by the measurement index
Whether portion's image, which needs, is filtered.The present embodiment can help to save the filtering processing of the image less to amount of noise
Step, the image only filtered to needs carry out the filter operation, can mention under the premise of improving the match cognization precision of image
The match cognization efficiency of hi-vision.
In a kind of mode that can be realized, whether the pixel r for detecting the subregion according to the following formula is noise
Point:
In formula, h (r) is the channel value of r-th of pixel of subgraph, hcIt (r) is the neighbouring of r-th of pixel of subgraph
The channel value of c-th of pixel in region, nrFor the pixel quantity in the adjacent domain of r-th of pixel of subgraph, hT
For preset channel value difference threshold value, z (r) be subgraph r-th of pixel gray value, z (max) be subgraph pixel most
High-gray level value, z (min) are the minimum gradation value of the pixel of subgraph,To judge value function, whenWhen,WhenWhen,
Indicate that r-th of pixel is noise spot when U>=0, when U<0 indicates that r-th of pixel is not noise spot.
The present embodiment determines whether pixel is noise spot with channel value difference and gray value, and determines noise spot based on this
Quantity calculates simplicity, improves the efficiency of noise spot judgement.
It is specific to execute when acquiring Standard User face image in a kind of mode that can be realized:
The server sends acquisition instructions to mobile terminal connected to it；
The server receives user's face image that the mobile terminal is sent according to the acquisition instructions；
The server carries out feature extraction to the user's face image sent according to the acquisition instructions, according to extraction
Feature calculation mass value；
If the mass value is not 0, the server using the user's face image sent according to the acquisition instructions as
The standard face image of user, and store to position corresponding in its database.
Wherein, if the mass value is 0, the server is sent to the mobile terminal for prompting user to resurvey
The information of user's face image.
Wherein, the calculation formula of the mass value are as follows:
Fb=V1(Eb-ET)×V2[Yb-YT]×V3[Gb]
In formula, FbIndicate the mass value of user's face image b, EbWhole image is accounted for for the face area of user's face image b
Ratio, ETFor preset first ratio lower limit, V1(Eb-ET) it is first to judge value function, work as Eb-ETWhen >=0, V1(Eb-ET)
=1, work as Eb-ETWhen < 0, V1(Eb-ET)=0；YbFor the edge sharpness of user's face image b, YTFor preset edge sharpness threshold
Value, V2[Yb-YT] it is second to judge value function, work as Yb-YTWhen > 0, V2[Yb-YT]=1, works as Yb-YTWhen≤0, V2[Yb-YT]=
0；GbFor the noise level of user's face image b, V3[Gb] it is that third judges value function, work as GbWhen > 1, VA(Gb)=0, works as Gb
When≤1, V3(Gb)=1.
The present embodiment carries out quality judging by the user's face image acquired to mobile terminal, and selection meets quality requirements
User's face image as standard face image, avoid image contributions subsequent face image that is of poor quality or not meeting ratio
Recognition efficiency, for subsequent face image it is quick identification lay a good foundation, and then be beneficial to raising inter-vehicle information system theme
The efficiency of setting；The calculation formula of mass value is devised, wherein to realize that the high-quality detection of standard face image provides measurement
Mode is advantageously implemented the quick detection of standard face image quality.
It is apparent to those skilled in the art that for convenience and simplicity of description, only with above-mentioned each function
