1. A method for recognizing a face, the method comprising:

  • acquiring at least two facial images of a to-be-recognized face under different illuminations using a near-infrared photographing device;

    generating at least one difference image based on a brightness difference between each two of the at least two facial images;

    determining a facial contour image of the to-be-recognized face based on the at least one difference image;

    inputting the at least two facial images, the at least one difference image, and the facial contour image into a pre-trained real face prediction value calculation model to obtain a real face prediction value of the to-be-recognized face, the real face prediction value calculation model being used to represent a corresponding relationship between the at least two facial images, the at least one difference image, the facial contour image and the real face prediction value; and

    outputting prompt information for indicating successful recognition of a real face, in response to determining the obtained real face prediction value being greater than a preset threshold.
