Abstract: The present invention relates to an image splicing method and apparatus. The image splicing method includes: acquiring a first image and a second image; determining a to-be-processed region within the overlapping region, where a region within the overlapping region except the to-be-processed region is a remaining region; obtaining a weight value of each adjacent pixel pair of the remaining region; setting a weight value of an adjacent pixel pair within the to-be-processed region; determining a splicing path having the least seam line intensity of all splicing paths; and performing image splicing on the first image and the second image along the optimal seam line. According to the image splicing method and apparatus of the present invention, a seam line can be excluded from a to-be-processed region, so as to ensure that the to-be-processed region is spliced naturally and to improve subjective perception of a user in viewing an image.

Abstract: In a network protection method, a network node, and a communications system provided in embodiments of the present disclosure, when signal degrade or signal fail occurs in a service transmission path, a communication status of a source node of a current protection segment is obtained, and whether to perform protection switching is determined according to the communication status of the source node and a communication status of a local communication path. This can avoid erroneous switching to some extent, thereby improving protection switching accuracy of a communications network.

Abstract: This application discloses example data sending methods and apparatuses, and an example FlexE switching system. In one example, when slice packets received include a SOP flag and an EOP flag of a same data packet, immediately data packet slices is restored in the slice packets to a FlexE data stream and the FlexE data stream is sent, or the data packet slices are restored in the slice packets to the FlexE data stream and the FlexE data stream is sent when a latency is greater than or equal to a first present duration. When the slice packets received include the SOP flag but do not include the EOP flag of a data packet, the data packet slices are restored in the slice packets and the FlexE data stream is sent when the latency reaches a second preset duration. The first preset duration is less than the second preset duration.
