Abstract

The invention comprises an intelligent terminal face unlocking method combined with expression recognition. Firstly, the face image is captured and preprocessed, then the image is processed by an Adaboost algorithm based on Haar feature; after filtering, feature extraction and feature dimension reduction, the feature is classified and recognized by a support vector machine SVM, and face recognition is carried out; the expression key frame is extracted and the expression recognition is carried out; if the recognition screen is unlocked successfully, the recognition failure is counted to reach the set number and the screen is locked. The invention integrates the visual recognition advanced technology such as face and expression, improves the complexity of face unlocking, greatly reduces thesuccess rate of cracking the terminal by using the methods such as video recording or dynamic picture recording without knowing the specific expression action, and is unable to unlock the screen.

Description

technical field [0001] The present invention relates to the technical field of smart screen unlocking, in particular to a face unlocking method for a smart terminal combined with facial expression recognition. Background technique [0002] In the "2017-2022 China Smartphone Market Supply and Demand Forecast and Investment Strategy Research Report", it is pointed out that the penetration rate of smartphones in my country has reached 58%, and smartphones have become an important channel for people to shop, communicate, study and work, and surf the Internet. A large amount of private data of users is stored in the mobile phone, such as photos and videos, office documents, consumption records, medical health and other data. If these data are leaked, it will inevitably lead to the loss of personal work, life and even economic property. As a portable device, mobile phones are easy to lose or be stolen by others. Therefore, how to prevent the disclosure of sensitive information in...
