Abstract: A face recognition method. The method includes: obtaining a face image to be recognized; extracting a face image feature based on the face image by using a pre-trained feature extraction network; extracting a plurality of facial geometric feature points from the face image to determine a plurality of feature point sets, where each of the plurality of feature point sets corresponds to one face part, and the feature point set includes at least one facial geometric feature point; obtaining a face topology structure feature based on the plurality of feature point sets, where the face topology structure feature is used to determine a relative location relationship between the plurality of feature point sets; and performing matching in a preset face database based on the face topology structure feature and the face image feature, to obtain a face recognition result.

Abstract: A data restoration method and apparatus, and a terminal, where the data restoration method includes monitoring whether an error occurs in original data stored in a read-only area of a memory when the terminal runs or loads a first operating system, loading a second operating system from the memory when an error occurs in the original data, where the second operating system provides a system restoration function, and obtaining an original data file corresponding to the original data, and restoring the original data to the read-only area of the memory according to the original data file when the terminal runs the second operating system. Hence, a terminal may automatically restore a system when an error occurs in data in a read-only area of a memory.

Abstract: A method and an apparatus for reading/writing data from/into a flash memory, and user equipment are presented. The method includes receiving a read data instruction, where the read data instruction includes a size of to-be-read data and a physical address of the to-be-read data in the flash memory; searching a buffer for the physical address; when the physical address is not found in the buffer, dividing a buffer data area from internal memory according to the size of the to-be-read data and an actual physical block size of the flash memory; and reading the to-be-read data from the flash memory according to the physical address and buffering the to-be-read data into the buffer data area.

Abstract: In one embodiment, a target tracking method includes: receiving a current frame of picture including a target object; determining, based on a drift determining model, whether a tracker drifts for tracking of the target object in the current frame of picture, where the drift determining model is obtained through modeling based on largest values of responses values of a training sample used to train the drift determining model, where the training sample is collected from a training picture that includes the target object, where the response value of the sample is a value indicating a probability that the training sample is the target object in the training picture; and outputting a tracking drift result, where the tracking drift result includes: drift is generated for the tracking of the target object, or no drift is generated for the tracking of the target object.

Abstract: Embodiments of the present disclosure relate to the field of computer data processing, and provide a data processing method and a smart device, which can effectively resolve a problem of abnormal rewriting of data in a read-only partition of an embedded multimedia card (eMMC) while ensuring that normal upgrading is not affected. The method includes receiving a write protection cancellation command sent by a central processing unit, executing the write protection cancellation command on a specified partition that is in the read-only partition and that is used to store an upgrade file, receiving the upgrade file sent by the central processing unit, writing the upgrade file to the specified partition, after completing writing the upgrade file, sending a write completion message to the central processing unit, receiving a write protection command sent by the central processing unit, and executing the write protection command on the specified partition.
