Abstract

The present invention provides a video marking method and device. The method includes: recording the target size of the target image, dividing the target matrix of the target image into each first sub-matrix, and using the eigenvalues ​​of each first sub-matrix to form a first vector; The obtained video stream is analyzed, and the original image data obtained by the analysis is encapsulated into each single-frame image; each single-frame image is marked in the following manner: the single-frame image is scanned pixel by pixel, and each image whose size is the target size is obtained. sub-image; for each sub-image, the matrix of the sub-image is divided into each second sub-matrix, and the second vector of the sub-image is formed with the eigenvalues ​​of each second sub-matrix; the second vector and the second vector of each sub-image are calculated A cosine similarity between vectors is used as the similarity of each sub-image; a target area where the sub-image with the highest similarity is located in the single frame image is determined; and a mark is added to the target area. By applying the embodiment of the present invention, the marking of the video stream by the mobile terminal is realized.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a video marking method and device. Background technique [0002] With the rapid development of surveillance technology, video data is increasing massively. In order to quickly determine the target to be analyzed from video data, video tagging technology has emerged as the times require. The target to be analyzed may be a person, a car, etc. that the user is interested in or wants to find. [0003] At present, there are few related researches on video tagging technology applied to mobile terminals (such as mobile phones), and the video tagging is usually completed by manual tagging on a computer. Therefore, it is necessary to design a video marking method to realize marking of video streams by mobile terminals. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and provide a video marking method and device, so as...
