Problems solved by technology

However, most of the current video applications are searched based on text matching, so a lot of text tags must be added to these videos, or only the title and description of the video can be searched
It can be seen that the purely text-based search method is relatively simple, and cannot accurately describe the video content, and it is easy to cause mismatched search results due to the mismatch between the title and the content.

Embodiment 1

[0024] figure 1 It is a flowchart of a video search method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation when responding to a detected video search instruction. The method can be executed by a video search device, and the video search device can be implemented in software and / or hardware. For example, the video search device can be configured in a computer device. Such as figure 1 As shown, the method includes:

[0025] S110: When a video search instruction is detected, obtain target picture information included in the video search instruction, and determine picture feature data according to the target picture information.

[0026] In this embodiment, the video search instruction may be a search instruction initiated by the user through the client to instruct to search for specified video content. The target picture information may be included in the video search instruction, and may represent the picture information of the vide...

Embodiment 2

[0047] figure 2 It is a flowchart of a video search method provided in the second embodiment of the present invention. This embodiment provides a preferred embodiment on the basis of the foregoing embodiment. Such as figure 2 As shown, the method includes:

[0048] S210. The client uploads the target picture and search conditions to the server.

[0049] S220: The server performs feature extraction of the target image to obtain image feature data.

[0050] The picture feature data of the target picture can be obtained through different methods.

[0051] In one embodiment, the binary value of the color picture can be represented by a three-dimensional array [h,w,3], the three-channel data is converted into single-channel data, and then the pixel average value is calculated, and the pixel value of each pixel is compared with the average value For comparison, less than the average value is recorded as 0, and greater than the average value is recorded as 1, and the binarized data conta...

Embodiment 3

[0064] image 3 It is a schematic structural diagram of a video search device provided in the third embodiment of the present invention. The video search device can be implemented by software and / or hardware. For example, the video search device can be configured in a computer device. Such as image 3 As shown, the device includes a picture feature determination module 310, a target segment determination module 320, and a response information determination module 330, wherein:

[0065] The picture feature determination module 310 is configured to, when a video search instruction is detected, obtain target picture information included in the video search instruction, and determine picture feature data according to the target picture information;

[0066] The target segment determination module 320 is configured to match the picture feature data with the scene feature data of the candidate scene segment, and determine a target scene segment matching the target picture information acc...

Abstract

The embodiment of the invention discloses a video search method and device, equipment and a medium, and the method comprises the steps: obtaining target picture information contained in a video searchinstruction when the video search instruction is detected, and determining picture feature data according to the target picture information; matching the picture feature data with scene feature dataof candidate scene segments, and determining a target scene segment matched with the target picture information according to a matching result; and taking a video corresponding to the target scene segment as response information of the video search instruction. According to the video search method provided by the embodiment of the invention, the corresponding video content can be determined according to the picture information in the video search instruction, the accuracy of video search is improved, and the search mode of video search is enriched.

Description

Technical field [0001] The embodiments of the present invention relate to the field of multimedia, and in particular to a video search method, device, equipment and medium. Background technique [0002] With the rapid development of the Internet, more and more video services and applications appear. Users can search for and watch videos they want to watch through video services. However, most of the current video application searches are based on text matching. Therefore, a large number of text tags must be made for these videos, or only the title and description of the video can be searched. It can be seen that the search method based solely on text is relatively simple and cannot accurately describe the video content, and it is easy to cause the search results to mismatch due to the mismatch between the title and the content. Summary of the invention [0003] The embodiments of the present invention provide a video search method, device, equipment, and medium, so as to improve ...
