Title:
METHOD AND DEVICE FOR GENERATING STATIC VIDEO ABSTRACT
Document Type and Number:
WIPO Patent Application WO/2018/137126
Kind Code:
A1
Abstract:
The present invention is applicable to the technical field of computers, and provides a method and device for generating a static video abstract. The method comprises : receiving a video to be processed entered by a user; pre-sampling, by means of a singular value decomposition algorithm, the video to be processed to extract candidate frames of the video to be processed; separately generating, according to a bag-of-word model algorithm, histograms for representing each candidate frame; clustering all histograms by means of a high density peak search algorithm denoted based on a video, and obtaining the clustered cluster center points; and generating, according to each cluster center point, a static video abstract of the video to be processed. According to the method, by means of generation of candidate frames and representation of histograms, redundant frames are removed more deeply, and cluster centers are adaptively generated during the cluster process without pre-setting the number of clusters and comprising the iteration process. The stability and adaptability of clustering are effectively improved and the time complexity of clustering is reduced, thereby effectively improving the generation efficiency and quality of a static video abstract.
