Embodiment Construction

[0014] The following is based on figure 1 and figure 2 A preferred embodiment of the present invention is given to describe the technical solution of the present invention in detail.

[0015] A method for face recognition of a mobile phone camera, comprising the steps of:

[0016] Step 1: Obtain the facial image of the mobile phone owner as a face recognition template;

[0017] Step 2: The camera of the mobile phone takes a photo of the face of the person who turns on the phone, and stores the photo;

[0018] Step 3: Calculate the correlation coefficient between this photo and different parts in the previous face recognition template;

[0019] Step 4: If the photo taken by the camera matches the previous face recognition template, it will automatically power on or unlock, otherwise it will not respond.

[0020] Wherein, in the photographing process, the pictures all adopt the grayscale image processing method. Use the threshold method to binarize the grayscale image of t...

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

technical field [0001] The invention relates to the application of a face recognition method of a camera, in particular to a method of using a camera of a mobile phone to recognize a face to determine permission to start / unlock. Background technique [0002] With the popularity of mobile phone users, mobile phones are not only used for telephone communication, but also contain a lot of personal privacy. Once the mobile phone is lost or some information is peeped, it will cause great losses. At present, there is no safe and reliable method for starting the mobile phone and unlocking the keys. Generally, it can be opened by pressing two keys, and there is no certain security. In order to protect personal information from leakage, it is more important to identify the mobile phone holder. Moreover, the camera function of the mobile phone has become universal and the technology is mature, and it is more convenient to use the camera for face recognition. Contents of the invent...
