Abstract: An electrocardiogram waveform signal 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. The extracting of the line segment includes extracting a line segment length Xi and a line segment width Yi of each signal line segment i of the K signal line segments, performing difference extension on the line segment length Xi and the line segment width Yi based on a preset length and a preset width, respectively, to obtain a normalized signal line segment j, and extracting fourth line segment data of the normalized signal line segment j.

Abstract: A face image detection method includes: recognizing facial features of a face image, and determining two pupil centers of the face image; connecting the two pupil centers, and determining a center point of a line segment whose endpoints are the two pupil centers; and selecting K columns of pixels from a local image region including the center point, calculating a gradient value of each pixel in each column of pixels, and generating K gradient vectors including gradient values of all columns of pixels, determining, based on a result of comparing the K gradient vectors with a specified threshold, whether glasses are worn on the face image.

Abstract: An emulated card selection method is implemented on a mobile device having a near field communication (NFC) 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 NFC 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 NFC emulated card.

Abstract: A method for calculating a tread frequency of a bicycle includes obtaining a first state of an acceleration signal in a first time window, determining a feature point set from the acceleration signal when the first state includes a riding state, where time distribution of a feature point in the feature point set meets a preset periodic distribution condition, and amplitude meets a physical rule, determining that the first state is the riding state when a feature point subset in the feature point set meets a preset reasonableness condition, and calculating, based on the feature point subset, a quantity of circles and a tread frequency that are in the first time window.

Abstract: In a method for determining a channel quality indicator (CQI) index, a user equipment (UE) determines quality of a channel between the UE and a base station. The UE sends a first index to the base station based on the quality of the channel. The first index is a CQI index corresponding to an average transmission rate supported by the channel. The UE sends an index difference to the base station based on the quality of the channel. The index difference indicates a difference between the first index and a second index. The second index is a CQI index corresponding to an instant transmission rate supported by the channel. A period for sending the first index is longer than a period for sending the index difference. A quantity of bits occupied by the index difference is less than a quantity of bits occupied by the first index.
