Embodiment 1

[0051] The method for establishing a content-based video search database provided by Embodiment 1 of the present invention, its process is as follows figure 1 shown, including the following steps:

[0052] Step S101: Obtain a video file in a storage state.

[0053] When there is a video file to be stored, it is temporarily stored in the video source file library, and the video file to be stored is obtained from the video source file library for subsequent analysis and processing. The status of the video files in the video source file library can be marked as pending storage status or unprocessed status.

[0054] Step S102: Start the video file analysis process, and select a video analysis item according to the requirements of video search.

[0055] After obtaining the video file in the storage state, start the analysis process of the file and mark it as the analysis state. According to the search requirements of video files, this search requirement can be set in advance, and...

Embodiment 2

[0069] The method for establishing a content-based video search database provided by Embodiment 2 of the present invention, its flow is as follows figure 1 shown, including the following steps:

[0070] Step S201: Obtain a video file in a storage state.

[0071] Step S202: Start the video file analysis process, and select a video analysis item according to the requirements of video search.

[0072] Step S203: Analyzing and processing the video file according to the selected analysis items, and extracting the analysis results of each analysis item.

[0073] The analysis results of each analysis item are recorded in the analysis result record file of each analysis item; the analysis result record file of each analysis item includes: the basic information of the video file to be stored, the basic information of the analysis item, and the characteristics of the analysis item information.

[0074] The video analysis result file includes the following contents:

[0075] Basic f...

Abstract

The invention discloses a content-based video search database establishment method and apparatus. The method comprises the steps of obtaining video files in a to-be-stored state; starting a video file analysis process, and according to video search demands, selecting video analysis items; according to the selected analysis items, performing analysis processing on the video files, and extracting analysis results of the analysis items; integrating the analysis results of the analysis items to generate a video analysis result; and transcoding the video files according to the video analysis results, and adding transcoded video files into a video search database for a user to search for and call. By performing analysis processing on stored videos, the video database convenient for the user to search for is established, so that the accuracy of video search by the user is improved and the user can find the required videos more quickly.

Description

technical field [0001] The invention belongs to video search processing technology, in particular to a method and device for establishing a content-based video search database. Background technique [0002] With the development of network video technology, network video is becoming more and more common. For users, it is a very common and commonly used operation to realize video search through the network and find the video file they want to play. In order for the user to accurately search for the desired video, some analysis and processing is usually performed on the video uploaded to the network. [0003] For example, the commonly used text-based video search technology usually requires manual annotation of video files, but now that there are more and more videos on the Internet, it is a lot of work to annotate a large number of video files one by one, requiring a lot of human resources. Human cost and low efficiency. [0004] The content-based video search technology ca...
