Problems solved by technology
However, the current video indexing methods are all based on the manual operation of the editor to treat the indexed video, that is, the editor can only manually input various indexing information at the parts that need to be indexed. Obviously, although this indexing method solves the problem of existing The problem of video retrieval can improve the efficiency of video retrieval after indexing, but the entire tagging process is also extremely time-consuming and laborious. Moreover, there are many identical or similar video sources on the Internet, and the indexed information will be partially repeated. Indexing is done manually every time, the work is highly repetitive and the indexing efficiency is low

Embodiment Construction
[0041] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0042] figure 1 It is a flowchart of a fast video indexing method based on a knowledge tree provided by the present invention. Before video indexing, the method includes a preset step: at least one knowledge tree is pre-established and stored for different video categories, and each video The category corresponds to a unique knowledge tree; each knowledge tree has several layers of nodes, and different nodes of the same layer are different descriptions of the same attribute of the video;
[0043] Such as figure 1 As shown in , the fast video indexing method based on the knowledge tree includes:

The invention discloses a video quick indexing method and device based on a knowledge tree and belongs to the technical field of audio-video technologies. The problem that according to an existing video indexing method, time and labor are wasted, and working repeatability is high is solved. According to the method, at least one knowledge tree is established for different video types in advance and is stored, and each video type corresponds to a unique knowledge tree; and each knowledge tree is provided with a plurality of node layers, and different nodes on the same layer are different description on the same attribute of video. The indexing method comprises the steps that the video type of video to be indexed is recognized; a knowledge tree corresponding to the video type of the video to be indexed is called; and for the current video segment, according to the nodes selected in the current knowledge tree by a user and the description from the last node layer of the nodes to root nodes, language labels are formed based on the language specification, and the language labels are added as the index of the current video segment. The method is used for carrying out indexing on video, efficiency is high, speed is high, and video marking work repeatability is lowered.
Description
technical field [0001] The invention relates to the technical field of audio and video, in particular to a knowledge tree-based fast video indexing method and device. Background technique [0002] With the rapid development of audio, video and the Internet, there are more and more websites using video as application services. In the face of massive multimedia resources, effective retrieval has become a major problem in information retrieval in recent years. [0003] Video data has the characteristics of large amount of information and poor structure. At present, in most online video services, users can only perform video retrieval based on simple video classification or simple text description. In order to find the target video segment, it is often necessary to continuously Forward or backward, the workload of retrieval is heavy, time-consuming and laborious. [0004] In order to solve the above problems, the prior art proposes a method of indexing the key content of the vi...
