Embodiment 1

[0028] figure 1 The implementation flow of the method for generating a static video summary provided by Embodiment 1 of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0029] In step S101, a video to be processed input by a user is received.

[0030] The embodiments of the present invention are applicable to platforms or smart devices capable of video processing. When a user needs to extract a static video summary of a video, the video can be used as a video to be processed and input to a platform or smart device that can currently perform video processing.

[0031] In step S102, the video to be processed is pre-sampled through a singular value decomposition algorithm to extract candidate frames of the video to be processed.

[0032] In the embodiment of the present invention, there may be quite a lot of repeated information between images of dif...

Abstract

The invention belongs to the technical field of computers, and provides a method and apparatus for generating a still video abstract. The method includes the following steps: receving a to-be-processed video which is input by a user; pre-sampling the to-be-processed video through a singular value decomposition algorithm so as to extract a candidate frame of the to-be-processed video; based on a bag of words model, separately generating a histogram which is used to represent each candidate frame; by means of a high intensity peak value search algorithm which is based on video representation, clustering all histograms, and acquiring a clustering center point after performing clustering; based on each clustering center point, generating a still video abstract of the to-be-processed video. The method herein can, by candidate frame generation and histogram representation, deeply remove redundant frames, can adaptively generate clustering center points in the clustering process, obviates the need for setting the number of clusters in advance and has no iterative process, effectively increases clustering stability and adaptivenes, reduces time complexity of clustering, and further effectively increases the efficiency and quality in generating still video abstracts.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for generating static video summaries. Background technique [0002] In recent years, with the development of multimedia technology, watching their favorite videos on the Internet has become an indispensable part of most people's daily life, but how to help people quickly obtain their favorite and interesting videos from a large number of videos, It remains a technically challenging problem. Static video summarization is an effective and classic method to solve this problem. This method obtains a static video summarization that can briefly represent the video content by removing redundant frames in the video. Users can learn about the general content of the video by watching the video summary, and judge whether they are interested in watching the entire video. [0003] At present, relevant researchers have proposed a variety of methods for stat...
