Method and apparatus for recognizing face

An apparatus for recognizing a face, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations 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.

A non-transitory computer storage medium storing a computer program the computer program when executed by one or more processors, causes the one or more processors to perform operations, the operations 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.
