Embodiment 1

[0068] figure 1 It is a schematic flowchart of a video scene entity recognition method provided in Embodiment 1 of the present application. This embodiment is applicable to the situation of identifying entities included in the video to be processed. The method can be executed by the video scene entity recognition device provided in Embodiment 3 of the present application, and the device can be implemented by software and / or hardware. Such as figure 1 As shown, the method may include:

[0069] S101. Acquire a target video to be processed and at least one target modality.

[0070] Wherein, the format of the target video includes but not limited to AVI, FLV, RMVB and WMV formats, and the target video is uploaded to the server by the user through the client. The target mode reflects what kind of information the user wants to perform entity recognition on the target video. For example, if the user wants to perform entity recognition on the text information of the target video, t...

Embodiment 2

[0106] figure 2 It is a schematic flowchart of a video scene entity recognition method provided in Embodiment 2 of the present application. This embodiment provides a specific implementation manner for the first embodiment above, such as figure 2 As shown, the method may include:

[0107] S201. Acquire a target video to be processed and at least one target modality.

[0108] S202. Extract at least one target modality feature of the target video.

[0109] S203. If the target modality includes a text modality, execute S204; if the target modality includes a visual modality, execute S208; if the target modality includes an audio modality, execute S209.

[0110] S204. Invoke the video domain classification algorithm provided by the server to determine the target domain to which the target video belongs.

[0111] Wherein, the target field reflects the category to which the target video content belongs, such as film and television, games, and sports. The video domain classifi...

Embodiment 3

[0167] image 3 It is a schematic structural diagram of a video scene entity recognition device 300 provided in Embodiment 3 of the present application, which can execute a video scene entity recognition method provided in any embodiment of the present application, and has corresponding functional modules and beneficial Effect. Such as image 3As shown, the device may include:

[0168] A target modality acquisition module 301, configured to acquire a target video to be processed and at least one target modality;

[0169] Target modality feature extraction module 302, for extracting at least one target modality feature of the target video;

[0170] The target entity recognition algorithm determination module 303 is configured to determine the target entity recognition algorithm to be used from at least two candidate entity recognition algorithms provided by the server according to the at least one target modality; wherein, the at least two candidate entity recognition algori...

Abstract

The invention discloses an entity identification method and device for a video scene, electronic equipment and a medium, and relates to the field of artificial intelligence. The method according to the invention comprises the steps of obtaining a to-be-processed target video and at least one target mode; extracting at least one target modal feature of the target video; determining a target entityidentification algorithm to be used from at least two candidate entity identification algorithms provided by the server according to the at least one target mode; wherein the at least two candidate entity identification algorithms are deployed in the server; and calling a target entity identification algorithm to perform entity identification on the at least one target modal feature to obtain a target entity included in the target video. According to the method and the device, identification of different modal entities of the target video is realized, the identification result accuracy is high, different service requirements can be met, and the universality is high.

Description

technical field [0001] The embodiments of the present application relate to computer technology, especially artificial intelligence technology, and specifically design methods, devices, electronic equipment and media for entity recognition of video scenes. Background technique [0002] With the development of information technology and the increasing popularity of various video apps, video will become the most important way of information dissemination, widely used in all aspects of interpersonal communication, social life, and industrial production. Faced with massive video content, manual processing alone cannot be completed. Therefore, it is urgent to realize intelligent understanding of video content through computer technology, and then automatically and intelligently classify and label videos. [0003] The traditional method is to perform entity recognition on the target video in a unimodal manner, such as performing entity recognition through pure video text features ...
