摘要： Embodiments of this application provide an image processing method, and relate to the field of computer vision technologies, to perform repair processing on a color image in a fog/haze/smoke extreme weather condition. The image processing method includes: obtaining a first depth map and a color image, where the first depth map and the color image are images respectively shot by a depth sensor and a camera for a same scene; determining an atmospheric light value; performing depth completion on the first depth map to obtain a second depth map, and determining a transmittance based on the second depth map; and performing repair processing on the color image based on the atmospheric light value and the transmittance. Due to depth completion, the second depth map has more depth information than the first depth map. In addition, the second depth map is used to determine the transmittance, and therefore, a transmittance of higher precision is obtained, thereby improving an image processing effect.

摘要： Embodiments of the present invention provide a communications method and apparatus. A network device sends a first synchronization signal/physical broadcast channel block on a first resource in resources corresponding to at least two candidate synchronization signal/physical broadcast channel blocks (SSBs), where the at least two candidate SSBs are respectively located at at least two frequencies in a single serving cell or a single bandwidth part in a frequency division multiplexing manner. The network device sends resource information of the first SSB. The foregoing solution provides a possibility of improving efficiency of sending and/or detecting an SSB.

摘要： This application provides a link failure recovery method and apparatus. When a link failure occurs and link recovery is performed, if a terminal device determines that no new link is identified, according to the method, the terminal device may report, to a network device, an identifier of a cell in which the link failure occurs and information indicating whether a new link is identified for each cell. The network device may reconfigure a new resource set based on the information, and notify the terminal device of the new resource set by using downlink control information DCI. In other words, a reference signal in another resource set is triggered by using the DCI, and the reference signal in the resource set is reported for link recovery. In this way, a link failure recovery probability can be increased, a link failure recovery delay can be reduced, and link failure recovery reliability can be improved.
