Abstract: A face recognition-based method includes, when a terminal detects a placement posture on the terminal, obtaining placement posture information of the terminal, where the placement posture information is used to determine a tilt angle of the terminal relative to a first plane; performing facial recognition on a user when determining that a tilt angle meets a preset range without notifying the user and regardless of detecting an action of the terminal other than obtaining the placement posture information; and opening the application when the facial recognition succeeds.

Abstract: An image capture method and apparatus obtains a preview image in a capture preview window, segments the preview image into N image blocks based on N objects included in the preview image, where N is a positive integer, determines M image blocks whose definitions do not meet a preset definition criterion from the N image blocks, where M is a positive integer less than or equal to N, adjusts an exposure parameter of each of the M image blocks, outputs prompt information when the definitions of the M image blocks meet the preset definition criterion. Prompt information prompts a user to capture the image, receives a capture instruction from the user, and captures the preview image in the capture preview window based on an adjusted exposure parameter.

Abstract: A method includes obtaining a filtered waveform signal, marking the waveform signal as K signal line segments based on monotonicity, extracting line segment data of each signal line segment, and determining a line segment matching template of the waveform signal based on the line segment data of each signal line segment, where the line segment matching template includes M consecutive signal line segments, and M is an integer less than K. The method further includes matching each of the K signal line segments with the M signal line segments included in the line segment matching template, and determining a target wave group of the waveform signal based on a matching result of each signal line segment. The method further includes determining periodic signal data of the waveform signal based on line segment data of the target wave group.

Abstract: An emulated card selection method is implemented on a mobile device having a near field communication (NEC) NFC function. A first emulated card and a second emulated card are configured on the mobile device, When detecting an NFC radio frequency field, the mobile device detects whether there is fingerprint input. The mobile device selects the first emulated card if there is the fingerprint input. The mobile device selects the second emulated card if there is no fingerprint input. The mobile device performs NEC interaction with the NFC card reader based on the selected first emulated card or second emulated card. The mobile device can automatically select an emulated card in different emulated cards based on a card swiping status when a user uses an NEC emulated card.
