Abstract: This application provides communication methods for a terminal device and a network side device. In an example method, a terminal device establishes a primary communication link with a network side device. The terminal device detects one or more other terminal devices, determines, from the one or more other terminal devices, one or more terminal devices as one or more coordinated communication devices, and notifies the network side device of information indicating that a coordinated communication device is used for coordinated communication. The terminal device establishes a device-to-device (D2D)-based virtual multiple-input-multiple-output (MIMO) communication connection with the coordinated communication device, to form, between the terminal device and the network side device, a coordinated communication link relayed by the coordinated communication device. The terminal device performs parallel communication with the network side device based on the primary communication link and the coordinated communication link, or performs communication based on the coordinated communication link.

Abstract: Embodiments of this application disclose an image processing method and an electronic device, to improve an image compositing effect obtained after foreground image processing. An embodiment of this application provides an image processing method, including: displaying a first key frame image obtained from a sequence frame video stream; obtaining a first foreground image and a first background image that are obtained after foreground and background separation processing is performed on the first key frame image; obtaining a second foreground image obtained after foreground image processing is performed on a first target object in the first foreground image; obtaining a third background image obtained after background repair processing is performed on the first background image by using a second background image, where the second background image is a background image included in a second key frame image, and the second key frame image is obtained by photographing, by using a camera, a target scene before the first key frame image is obtained; and obtaining a first key frame image obtained after foreground and background compositing processing is performed on the second foreground image and the third background image.
