InactiveCN101393598ACost unchangedImprove confidentialityCharacter and pattern recognitionRadio/inductive link selection arrangementsPattern recognitionFace detection
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.
