Abstract: The disclosure provides gesture recognition methods and apparatuses, and relate to the field of artificial intelligence. One example gesture recognition method includes obtaining an image stream, and determining, based on a plurality of consecutive frames of hand images in the image stream, whether a user makes a preparatory action. When the user makes the preparatory action, continuing to obtain an image stream, and determining a gesture action of the user based on a plurality of consecutive frames of hand images in the continuously obtained image stream. Next, further responding to the gesture action to implement gesture interaction with the user. In this application, in order to reduce the erroneous recognition occurring in a gesture recognition process, the preparatory action is determined before gesture recognition is performed.

Abstract: This application provides a signal transmission method. The method includes: transmitting an SRS of the first network from three antennas: a third antenna, a fourth antenna, and a fifth antenna in turn; and inputting the SRS and a second signal of the second network to a combiner, where the combiner combines the two signals and then transmits a combined signal from a multiplexed first antenna. In this way, the SRS is transmitted by using four paths in turn. This can ensure that transmission of the second signal is not interrupted in a process of transmitting the SRS of the first network by using the four paths in turn, so that a service of the second network is not interrupted.

Abstract: Embodiments of this disclosure provide an electronic apparatus and an image processing method of the electronic apparatus. The electronic apparatus includes: an artificial intelligence (AI) processor, configured to perform first image signal processing on a first image signal to obtain a second image signal, where the first image signal is obtained based on image data output by an image sensor; and an image signal processor (ISP), configured to perform second image signal processing on the second image signal to obtain an image processing result. In this way, image processing can be flexibly performed by the ISP in combination with the AI processor, and the image processing result is improved.

Abstract: An antenna switching circuit, electronic device and method. The switching circuit includes a radio frequency processor, a radio frequency front-end, a first switch, and an antenna system with a plurality of antennas. The radio frequency processor receives a first radio frequency signal, generates a second radio frequency signal based on a loss value of the first switch, and transmits the second radio frequency signal to the first switch. The first switch selects, from a plurality of radio frequency channels in the radio frequency front-end, a radio frequency channel coupled with the radio frequency processor, and transmits the second radio frequency signal to a radio frequency channel. The radio frequency front-end receives and processes the second radio frequency signal to generate a third radio frequency signal and transmits it to the antenna system, which outputs the third radio frequency signal.
