Patent Images

1. a biopsy method, comprises the following steps:

  • Obtain the facial image of multiple recognition sample, extract the face characteristic of multiple recognition sample according to the facial key point changing features of the facial image of described multiple recognition sample;

    Face characteristic based on described multiple recognition sample calculates the In vivo detection score of multiple recognition sample;

    In vivo detection score according to multiple recognition sample obtains live body judgment threshold;

    Obtain the facial image of object to be identified, extract the face characteristic of object to be identified according to the facial key point changing features of the facial image of described object to be identified;

    Face characteristic based on object to be identified calculates the In vivo detection score of object to be identified;

    Judge whether the In vivo detection score of object to be identified is more than or equal to live body judgment threshold, if so, then judge that object to be identified is live body.
