Abstract

The invention discloses a method for determining whether to permit starting up and unlocking a mobile phone by identifying a human face by a mobile phone camera. The method makes use of a human face detection method based on a gray level image and comprises the following steps: firstly, establishing a standard human face identifying template (a face image template for a mobile phone user); secondly, taking a photograph of the face of an operator by the camera before starting up or unlocking the mobile phone so that mobile phone software can automatically perform a global search of the input image and calculate the related coefficient of different parts between the image and the standard human face identifying template; and thirdly, judging whether the image accords with a human face image in the template according to a preset threshold value. If the image accords with the human face image in the template, the mobile phone is started up or unlocked automatically, otherwise, the mobile phone prompts a user that the starting up or the unlocking is failed.

Description

Utilize mobile phone cam recognition of face to be decided the method that allows start/release
Technical field
The present invention relates to a kind of application of face identification method of camera, particularly a kind of camera of mobile phone that utilizes decides the method that allows start/release to recognition of face.
Background technology
Along with popularizing of cellphone subscriber, mobile phone has been not only the effect of telephone communication now, and the mobile phone the inside has also comprised a lot of individuals' privacy.In case mobile phone is lost or some information are peeped, and will cause very big loss.The start and all safe and reliable without comparison method of button release of mobile phone generally all are just can open by two buttons at present, do not have certain security.In order to protect personal information not leak outside, even more important to mobile phone holder's identification.And mobile phone has camera function and had ubiquity and technology maturation, utilizes camera more convenient to recognition of face.
Summary of the invention
The purpose of this invention is to provide a kind of recognition of face that utilizes mobile phone cam to determine whether allowing starting shooting/method of release, with people's face whether with machine in recognition of face standard module coupling as starting shooting and the foundation of release.
The objective of the invention is to be achieved through the following technical solutions:
A kind of recognition of face that utilizes mobile phone cam determines whether allowing starting shooting/method of release, comprise the steps:
Step 1: obtain mobile phone owner's face-image, as the recognition of face template;
Step 2: mobile phone cam carries out face to start person takes pictures, and stores this photo;
Step 3: the related coefficient of calculating different piece in this photo and the previous recognition of face template;
Step 4: result of calculation is complementary with regard to Auto Power On or release as if both, otherwise will not respond.
Wherein, the shooting process of the facial image that relates to, picture are all taked the disposal route of gray level image, use threshold method that colour of skin gray level image is carried out binaryzation, and face are separated from the colour of skin.
Positive progressive effect of the present invention is: can keep obtaining higher confidentiality under the constant substantially situation of mobile phone cost.
Description of drawings
Fig. 1 is face identification functions of the present invention and the process flow diagram of setting up face recognition module;
Fig. 2 is the start or the release process flow diagram of recognition of face of the present invention.
Embodiment
Provide a preferred embodiment of the present invention according to Fig. 1 and Fig. 2 below, in order to describe technical scheme of the present invention in detail.
A kind of method of recognition of face of mobile phone cam comprises the steps:
Step 1: obtain mobile phone owner's face-image, as the recognition of face template;
Step 2: mobile phone cam carries out face to start person takes pictures, and stores this photo;
Step 3: the related coefficient of calculating different piece in this photo and the previous recognition of face template;
Step 4:, otherwise will not respond if camera is taken pictures and previous recognition of face template is complementary with regard to Auto Power On or release.
Wherein, described shooting process, picture are all taked the disposal route of gray level image.Use threshold method that colour of skin gray level image is carried out binaryzation, face are separated from the colour of skin.
Wherein, coloured image changes gray level image into, and gray-scale value belongs to the possibility of skin area corresponding to this point, by choosing suitable threshold value, further changes gray level image into bianry image then.
Wherein, represent skin area and non-skin area respectively with 0,1 in the bianry image.
Wherein, the storage of photo is carried out with the BMP form, and the data of BMP form can keep original image information well, for analysis.
For the identification of people's face, the present invention extracts the position and the shape of facial principal character, as the relevant information of major organs such as eyes, face on the basis that people's face detects.Their accurate location is the key of identification.Utilizing eyes is upper left side and this characteristic of top-right gray scale paddy district at face center in the facial zone, can accurately locate two eye pupil centers apace.Thereupon, relevant information such as eyes and face can obtain.
People's face comparison: according to the result of facial Feature Localization, compare with recognition of face template in the mobile phone, judge the identity information of this people's face, if degree of conforming to reaches more than 90%, then think and passed through the checking of mobile phone and opened mobile phone or release, otherwise will not respond.
In mobile phone, the facial photograph that before should store the mobile phone holder according to the present invention is as recognition template, and in mobile phone power-on or release, the present invention utilizes preposition camera that the mobile phone holder is taken pictures.Mobile phone carries out the conversion of image and the identification of face automatically after the storage, and now the pixel of mobile phone cam is more and more higher, 1,300,000,2,000,000,3,000,000 can be found everywhere.This recognition of face accuracy rate to camera also improves.So the recognition of face of mobile phone cam is used for start/release, be more suitable for using the mobile phone of camera for high pixel.
Characteristics such as this algorithm is applicable in the mobile phone of band camera, and influence, the robustness that have that calculated amount is little, speed is fast, be easy to realize real-time processing, not changed by countenance is good.The present invention has limited other people the improper operation to mobile phone, thereby avoids information to leak outside, and also can effectively prevent the criminal activity that utilizes mobile phone to carry out.

Claims (5)
