Abstract

The invention provides a video subtitle screening method, device and equipment and a storage medium, and relates to the technical field of multimedia, and the method comprises the steps: obtaining thecharacter information of a plurality of frames of video images corresponding to a video subtitle stream, and combining the character information of each frame of video image to obtain a correspondingsubtitle text block; according to the attribute characteristics of the subtitle character blocks, extracting and collecting the subtitle character blocks meeting a preset condition to obtain a subtitle group; calculating sentence confidence of each subtitle character block in the subtitle group, and selecting a target subtitle character block from the subtitle group according to the sentence confidence; and taking the character corresponding to the target subtitle character block as a reference subtitle, and calibrating the reference subtitle to obtain a final subtitle. According to the technical scheme, high-quality video subtitles can be accurately screened out, and the video subtitle screening efficiency is improved.

Description

technical field [0001] The present application relates to the field of multimedia, and in particular, the present application relates to a method, device, equipment and storage medium for screening video subtitles. Background technique [0002] With the development of digital media technology, video has become an indispensable part of people's daily life. In order to analyze the information in the video, such as sound, text and image, etc., the information in the video needs to be obtained. [0003] In the related art, in order to obtain subtitle information in a video to analyze the content of the video, an optical character recognition (Optical Character Recognition, OCR) technology may be used to recognize characters on the video screen as the subtitle of the video. [0004] In order to ensure the accuracy of OCR recognition, it is necessary to take screenshots of the video several times per second, so that the recognized subtitles have a certain degree of redundancy, th...
