Abstract: Embodiments of this disclosure relate to the multimedia processing field, and provide a video frame interpolation method, apparatus, and a device. In the video frame interpolation method in this disclosure, a first image at first time, a second image at second time, and sensor data captured by a dynamic vision sensor apparatus are obtained, and the sensor data includes dynamic event data between the first time and the second time. At least one target image is determined based on the first image, the second image, and the sensor data, where the at least one target image is an image corresponding to at least one target time between the first time and the second time. The dynamic event data is used to help compensate for motion information missing from existing image data. This implements accurate prediction of an intermediate image, and improves image prediction effect.

Abstract: Example methods and apparatus for managing a network device are described. One example method includes obtaining a static dataset and generating a knowledge corpus based on the static dataset, where the knowledge corpus includes information for managing a network device. The static dataset indicates how to manage the network device, and the static dataset includes data that is generated independent of a device interaction process.

Abstract: A data storage method and apparatus, and a storage system are provided. The method is applied to a storage system. The storage system includes at least one first memory and a second memory. The at least one first memory includes a plurality of storage areas. Garbage collection is performed based on each of the plurality of storage areas. In the method, a time length between the earliest expiration time and the latest expiration time in expiration time of valid data stored in a target storage area is limited to be less than or equal to a preset time length, so that the expiration time of the valid data stored in the target storage area is comparatively centralized.

Abstract: The present disclosure relates to optical flow estimation methods and apparatuses. One example method includes obtaining a first image frame and a second image frame, where the first image frame and the second image frame are any two adjacent image frames in an image sequence, and the image sequence is obtained by photographing a target scene. A first event frame is obtained, where the first event frame is used to describe a luminance change of the target scene within a time period from the first image frame to the second image frame. A target optical flow is determined based on the first image frame, the second image frame, and the first event frame, where the target optical flow is an optical flow from the first image frame to a target moment, and the target moment is any moment between the first image frame and the second image frame.

Abstract: This application provides an example multi-band communication method and an example apparatus. One example method includes a first device receives a first frame sent by a second device, where the first frame carries request information used to request to perform authentication, association in at least two bands, or reassociation in the at least two bands. The example method also includes based on the request information carried in the first frame, the first device authenticates, the first device is associated with the second device in the at least two bands, or the first device is reassociated with the second device in the at least two bands.
