Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] Because the essence of video quick preview technology is to obtain as much information as possible in the video in the shortest time. Take a 120-minute movie as an example, assuming that there are 30 shots in it, and each shot is 4 minutes on average, and now it is required to know the information of the movie within 4 minutes. The first method is to spend 4 minutes watching one of the shots; the second method is to watch each shot for 8 seconds, and then jump to the next shot, which takes a total of 4 minutes. Obviously, the second viewing method can obtain more information. Therefore, th...

Abstract

The invention relates to the electronic communications and video image processing field, and provides a video summary generation method, a system and a device. The method comprises the following steps: A, to receive and divide the inputted video to get candidate time point sequences; B, through the scene segmentation algorithm, to get a jumping time point sequence selected from the candidate time point sequences; C, according to the jumping time point sequence, to extract the video segment corresponding to each jumping time point, and to combine the all the video segments into a video summary and output the summary. In the video summary generation process, the invention firstly acquires the eigenvector of each video frame and selects the jumping time point sequence through hierarchical clustering, and finally extracts the corresponding video frames to form the video summary based on the jumping time point sequence, so as to cover the scene as much as possible and achieve the biggest difference among the video frames to enhance the completeness of the information of the video summary; in addition, the invention has no requirements to video types so as to improve the universality in technology application.

Description

technical field [0001] The present invention relates to electronic communication and video image processing, more specifically, to a method, system and equipment for generating video summaries. Background technique [0002] With the development of computer technology and multimedia technology, people come into contact with increasingly rich multimedia resources. However, everyone's time is limited, and it is impossible to browse all the multimedia resources they come into contact with, so they need to quickly find the information they are interested in in the vast information resources. It's like when people read an article, they can first look at the abstract, and then determine whether they are interested in the article; when browsing a large number of pictures, they can first look at the thumbnails, and then determine the pictures of interest. However, when people watch a video, there is no particularly effective method to quickly and comprehensively learn the informatio...
