Abstract

The invention discloses a method and a device for generating a template, and a video update method and device. The method for generating the template comprises the following steps of: determining the first target area of each template picture in a template video; carrying out statistics on a first similarity between the first target areas of any two template pictures in the template video; according to the first similarity, selecting a plurality of template key frame pictures; decomposing each template key frame picture into image blocks of RGB (Red, Green and Blue) three single channels; independently obtaining the matrix relation graph of each template key frame picture in the image block of each single channel in the RGB three single channels; according to the matrix relation graph, obtaining the feature vector of each template key frame picture; carrying out PCA (Principal Component Analysis) processing on the feature vector of each template key frame picture to obtain the template video fingerprint of each template key frame picture; and generating the video template of the template video. Through the technical scheme of the invention, video repeatability detection can be accurately carried out, and the accuracy and the efficiency of the video repeatability detection are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a template generating method, a template generating device, a video updating method and a video updating device.
