Abstract: Embodiments of this application provide a method for eliminating an interference pattern in an image, and an apparatus, and relate to the image processing field, which can eliminate an interference pattern in an image collected by a ToF sensor arranged under a display screen of an electronic device. The method includes: obtaining, by the electronic device in advance, K interference patterns corresponding to K different values of a same parameter one by one; collecting, by the electronic device, a first image, and measuring a first parameter value in a case that the first image is collected; determining a first interference pattern in the K interference patterns according to the first parameter value, and determining the second interference pattern according to the first interference pattern; and eliminating the second interference pattern in the first image, so that the processed first image does not include the interference pattern. Therefore, the ToF sensor can be arranged under the display screen of the electronic device, and measurement precision the same as that when the ToF sensor is arranged on a frame can be achieved.

Abstract: Embodiments of this application provide a face recognition method and apparatus, including: obtaining TOF data; processing the TOF data into a TOF image in a TEE; and performing face recognition by using the TOF image, to obtain a recognition result. Because the TOF data is used for face recognition, higher security is achieved. Implementation in the TEE can further improve the security.
