Abstract: An image prediction method and device are disclosed. The method includes: obtaining a first reference unit of an image unit, where respective predicted images are obtained for the image unit and the first reference unit by using a same affine model; obtaining motion information of basic motion compensation units at two or more preset positions in the first reference unit; and obtaining motion information of a basic motion compensation unit of the image unit according to the motion information. In this way, motion information of the first reference unit using a same affine motion prediction model is reused, and a more accurate motion vector of a current image unit is obtained, improving prediction accuracy and maintaining encoding and decoding complexity, thereby improving encoding and decoding performance.

Abstract: A video image decoding method includes: parsing a high-resolution image bitstream, to generate a reconstructed image of a first-type sub-image and auxiliary information of the first-type sub-image, where the auxiliary information represents dimension information of the sub-image and position information of the sub-image in a to-be-reconstructed image, the sub-image is a pixel set of any continuous area in the to-be-reconstructed image, and sub-images of the to-be-reconstructed image do not overlap with each other; when a complete reconstructed image fails to be obtained based on the reconstructed image of the first-type sub-image, parsing a low-resolution image bitstream, to generate a reconstructed image of a second-type sub-image, where the second-type sub-image has a resolution the same as that of the first-type sub-image; and splicing the reconstructed image of the first-type sub-image and the reconstructed image of the second-type sub-image based on the auxiliary information, to generate the reconstructed image.

Abstract: Implementations of path planning methods, devices, and systems are disclosed. In an implementation, a first velocity set of a target vehicle is determined according to a first velocity set of a reference vehicle of the target vehicle. The first velocity set includes velocity information in one-to-one correspondence to at least one time point. The first segment is a next segment of a current driving segment of the target vehicle, and the reference vehicle is a preceding vehicle of the target vehicle; and sending the first velocity set of the target vehicle to the target vehicle. Lane-level path planning can be implemented for a road lane, a ramp, and a crossroad etc. By planning a driving velocity of a vehicle in advance, overall traffic efficiency can be improved and a possibility of traffic accidents can be reduced.
