Problems solved by technology

During video playback, with the continuous development of video content, the number of key frame images gradually increases, and the form background formed based on key frame images is always in a state of dynamic increase. When new concepts are added to the form background, the concept grid changes can become very complex

Embodiment Construction

[0079] To make the technical solutions and advantages of the present invention clearer, the following describes the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention:

[0080] Such as figure 1 The shown method for expressing video content structure based on an incremental concept tree specifically includes the following steps:

[0081] S1. Object topology representation of formal background

[0082] Taking the short video "Pulling Carrots" as the experimental object, we intercepted 18 key frame images to express the video content structure, and named them with numbers 1 to 18 in chronological order and arranged them in figure 2 in. The selection condition of the key frame image is: a frame image whose scene remains unchanged for a long time in a period of time is used as the key frame image of the interval.

[0083] The above 18 key frame images are processe...

Abstract

The invention discloses a video content structure representation method based on an incremental concept tree. The video content structure representation method comprises the following steps: converting a video time sequence change into a dynamic form background, carrying out object topology representation on the form background, analyzing the influence of a newly added object on object topology, and classifying the newly added object according to different generated influences; analyzing the relationship between the objects on the premise of taking the newly added object characteristics as thesubstrate; determining a sub-tree which can grow after the object is newly added, and growing the sub-tree at a corresponding position in the concept tree through a sub-tree growth algorithm of the newly added object; completing the updating of the concept tree through a concept tree updating algorithm, thereby carrying out the structural representation of the video content.

Description

Technical field [0001] The present invention relates to a method for expressing a video content structure, in particular to a method for expressing a video content structure based on an incremental concept tree. Background technique [0002] With the increasing popularity of smart terminals, people are increasingly accustomed to receiving and transmitting messages through the Internet, and multimedia data on the Internet has exploded, especially video data, which has become an increasingly widely used media form. Video is an unstructured data stream that can record and retain various information in space and time. In recent years, research in the field of video has become more and more in-depth, such as video mining, video understanding, video description, etc., structured representation of video content As its basic research content, it has always been one of the research hotspots in the field of video analysis. [0003] As an important tool for studying the relationship between ...
