Abstract: A target tracking apparatus includes an image sensor, a controller, an image signal processor, and an event processor. A processing capability of the image signal processor is different from a processing capability of the event processor. The image sensor is configured to: capture a first raw (RAW) image, and send the first raw image to the controller. The controller is configured to: determine a motion distance, in two adjacent frames of raw images, of a target object in the first raw image, where the first raw image is a next frame of image of the two adjacent frames of raw images; determine a target processor from the image signal processor and the event processor based on the motion distance, where a processing capability of the target processor matches the motion distance; and perform target tracking on the target object based on the first raw image by using the target processor.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a session management function (SMF) receives a first message including a multicast address from a terminal, sends a second message to a network registration function (NRF), where the second message is used to query for an SMF that establishes a multicast session for a multicast service corresponding to the multicast address, receives, from the NRF, a third message indicating that the SMF that establishes the multicast session for the multicast service corresponding to the multicast address is not found, and sends, to the terminal, a fourth message indicating that the terminal is rejected to join the multicast session corresponding to the multicast address.

Abstract: This application provides a communication method and apparatus, to improve data transmission efficiency. The communication method and apparatus may be used in systems such as a 5G system and a V2X system. The method includes: After receiving, through a first unicast session, a request message for adding a first terminal to a multicast group, a first session management network element sends second information based on first information. The second information is for requesting a first user plane network element to send multicast data not through the first unicast session or not to send first signaling to a data network. The first signaling is for establishing a second tunnel used by the data network to send the multicast data to the first user plane network element, and the first user plane network element is a user plane network element corresponding to the first unicast session.
