Embodiment 1

[0058] This embodiment provides a video summarization method for self-made videos, such as figure 1 shown, including steps:

[0059] S11: Segment the original video using a dense nearest neighbor clustering method to generate video segments;

[0060] S12: Evaluate the importance level of the video segment;

[0061] S13: Sampling video clips within a preset range through a greedy selection strategy.

[0062]Video summarization technology can be applied in real life, such as analyzing surveillance video, video browsing, motion recognition, and generating video logs. It will bring revolutionary technological progress to the fields of transportation and public security. The scientific community and the industry generally believe that the future video system, especially for user-made videos, will use the video summarization system, so this is a technology with broad application prospects, and it will be used in future traffic and public security monitoring equipment. is widely u...

Embodiment 2

[0112] This embodiment provides a video summarization system for self-made videos, such as figure 2 shown, including:

[0113] Segmentation module 21, for using dense nearest neighbor clustering method to segment original video to generate video clips;

[0114] An evaluation module 22, configured to evaluate the importance level of the video segment;

[0115] The generating module 23 is configured to sample video clips within a preset range through a greedy selection strategy.

[0116] This embodiment proposes an unsupervised learning video summarization system based on repeated picture detection and relative representation degree of video frames for user-made videos. This embodiment constructs a system based on a graph model, in which the vertices correspond to video frames, and the edges correspond to the relative entropy of the semantic probability distribution of every two frames, and the video frames or segments are sorted according to the amount of information contain...

Abstract

The invention discloses a video abstract method and system used for a self-made video. The video abstract method and system is used for solving the problems of time and labor consumption of generatinga video abstract of the self-made video at present. The method comprises the steps of segmenting an original video by using a dense neighbor clustering method to generate multiple video clips; assessing important levels of the video clips; and sampling the video clips with the important levels in a preset range through a greedy selection policy to generate the video abstract. The video clips aresubjected to the important level assessment through an unsupervised learning method, so that the use of the video abstract generated by continuous detailed and accurate video frames is ensured; and the manually tagged video abstract is not required to assist in analyzing a video internal structure, so that a large amount of labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of video summarization, in particular to a video summarization method and system for self-made videos. Background technique [0002] With the development and popularization of smart phones and camera equipment, videos can be acquired and stored more easily. Thereby, a large amount of user-made video data is also produced thereupon. Therefore, the demand for video retrieval also increases, and consumes a lot of time, manpower and material resources. However, users usually seldom consider the duration, content, and viewing angle selection when recording videos, resulting in self-made videos including lengthy, poor-quality, and unedited content (such as lighting, shaking, dynamic background, etc.). [0003] In this context, video summarization technology plays an important role in assisting users to quickly browse important events. Video summarization techniques aim to sample the original video to reduce its...
