Embodiment 1

[0040] figure 1 It is a schematic flow chart of a hot word extraction method provided by Embodiment 1 of the present disclosure. This embodiment of the present disclosure is suitable for determining the hot word vocabulary of the video based on each video frame in the video, and then in the process of speech-to-text conversion, it can be determined and Hot word vocabulary corresponding to voice information, in order to improve the accuracy of speech-to-text conversion, the method can be executed by a device for extracting hot words, which can be implemented in the form of software and / or hardware, and optionally, electronically device, the electronic device may be a mobile terminal, PC or server. The implementation of the technical solutions of the embodiments of the present disclosure can be realized through the cooperation of the client and / or the server.

[0041] Such as figure 1 , the method of this embodiment includes:

[0042] S110. Determine a target key video frame....

Embodiment 2

[0067] figure 2 It is a schematic flowchart of a method for extracting hot words provided in Embodiment 2 of the present disclosure. Based on the foregoing embodiments, the target key video frame may be determined according to the current video frame and at least one historical key video frame before the current video frame. Wherein, terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated here.

[0068] Such as figure 2 As shown, the method includes:

[0069] S210. Acquire the current video frame and at least one historical key video frame before the current video frame.

[0070] It should be noted that in each video, the content of adjacent video frames will be repeated. In order to avoid the problem of resource waste caused by the processing of repeated video frames, the current video frame can be determined before processing each video frame in turn. Whether the frame is similar to the previous key video frame, so as to d...

Embodiment 3

[0085] image 3 It is a schematic flowchart of a method for extracting hot words provided in Embodiment 3 of the present disclosure. Based on the foregoing embodiments, it can be known that determining the target key video frame is determined based on the similarity value between the current video frame and historical key video frames. For determining the similarity value between the current video frame and the historical key video frame, refer to the technical solution provided in this embodiment. Wherein, technical terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated here.

[0086] like image 3 As shown, the methods include:

[0087] S310. Acquire the current video frame and at least one historical key video frame before the current video frame.

[0088] S320. Determine at least one extremum point in the current video frame.

[0089] It should be noted that, before determining whether the current video frame is the targ...

Abstract

Embodiments of the disclosure provide a method and device for extracting hot words, electronic equipment and a storage medium. The method comprises the steps of determining a target key video frame; determining each target area in the target key video frame based on the target key video frame; determining a target content in the target key video frame based on the target area; and determining a hot word of the target key video frame by processing the target content. According to the technical scheme of the embodiment of the invention, the target content in the key video frame is determined byprocessing the determined key video frame, so that the hot word vocabulary of the video to which the target content belongs is determined based on the target content, and the hot word vocabulary corresponding to the voice information is determined during voice-to-character processing; and the technical effect of improving the accuracy and high efficiency of voice-to-character conversion is achieved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method, device, electronic equipment, and medium for extracting hot words. Background technique [0002] With the development of Internet communication technology, more and more users tend to communicate or communicate online. [0003] When communicating online, the user needs to manually determine the core of the current video discussion and the core vocabulary corresponding to the video conference according to the audio content and / or the content displayed on the display interface. [0004] However, in the actual application process, there is a technical problem that the user cannot understand the meeting content well, resulting in inaccurate determined core content, and thus low interaction efficiency. Contents of the invention [0005] The present disclosure provides a method, device, electronic device, and storage medium for extracting hot ...
