In a kind of onboard system multi-user access method and device of above-described embodiment, by user's face image with
The standard face image carries out match cognization, comprising:
The face area is divided at least two subregions, root by the face area for extracting user's face image
The noise level of the face area is calculated according to the noise spot quantity of subregion:
In formula, γ indicates the noise level of the face area, miFor the noise of i-th of subregion of the face area
Point quantity, Ψ are the subregion quantity of the face area；
If the noise level of the face area is greater than preset noise level threshold value, the face area is filtered
Processing.
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 c for detecting the subregion according to the following formula is noise
Point:
In formula, h (c) is the channel value of c-th of pixel of subregion, hxIt (c) is the neighbour of c-th of pixel of subregion
The channel value of x-th of pixel in nearly 2 × 2 region, hTTo preset channel value difference threshold value, when σ >=0, indicates c-th of pixel
Point is noise spot, and when σ < 0 indicates that c-th of pixel is not noise spot.
The present embodiment determines whether pixel is noise spot with channel value difference, and the quantity of noise spot is determined based on this, meter
Simplicity is calculated, the efficiency of noise spot judgement is improved.
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:
By=f1(Vy-VT)×f2[Ry-RT]×f3[γy-γT]
In formula, ByIndicate the mass value of user's face image y, VyWhole image is accounted for for eye areas in user's face image y
Ratio, VTFor preset first ratio lower limit, f1(Vy-VT) it is first to judge value function, work as Vy-VTWhen >=0, f1(Vy-VT)
=1, work as Vy-VTWhen < 0, f1(Vy-VT)=0；RyFor the edge sharpness of user's face image y, RTFor preset edge sharpness threshold
Value, f2[Ry-RT] it is second to judge value function, work as Ry-RTWhen > 0, f2[Ry-RT]=1, works as Ry-RTWhen≤0, f2[Ry-RT]=
0；γyFor the noise level of user's face image y, γTFor preset noise level threshold value, f3[γy-γT] it is that third judgement takes
Value function works as γy-γTWhen >=0, f3(γy-γT)=0, works as γy-γTWhen < 0, f3(γy-γT)=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 identify lay a good foundation；The calculation formula of mass value is wherein devised, is real
The high-quality detection of existing standard face image provides measurement mode, is advantageously implemented the quick detection of standard face image quality.
