Description

technical field [0001] The invention relates to the architecture of a high-definition video processing unit, and belongs to the technical field of high-definition video processing. Background technique [0002] With the development of video and image-related industries and the construction of large-scale projects such as safe cities, intelligent and convenient video image processing technology has attracted more and more attention. Video image processing technology is derived from computer vision technology, and the acquisition process of video images is the basis of computer vision technology. By analyzing the video image sequence collected by the camera or image acquisition sensor, the target positioning, target recognition, target tracking and other operations in a specific scene can be achieved, and the behavior of the target can be understood and described on this basis. [0003] The research on video image processing technology is becoming more and more mature, and th...
