Abstract

The invention relates to the technical field of video processing, and discloses a method for video subtitle recognition, which comprises the following steps of: performing character recognition on a plurality of video frames to obtain all textboxes in each video frame; determining a plurality of textbox sets according to the occurrence frequency of the textbox height; calculating a textbox width mean square error of each textbox set; and determining the subtitles according to the width mean square error of each textbox. Since the heights of the textboxes in the video are the same, but the widths of the textboxes in different video frames are different, the textboxes of the video subtitles can be accurately identified through the heights and the widths of the textboxes. When different types of video subtitles are identified, information such as video sizes and subtitle positions does not need to be considered, and subtitle classification does not need to be carried out through manual annotation. The invention further discloses a video subtitle recognition device, electronic equipment and a storage medium.

Description

technical field [0001] The present application relates to the technical field of video processing, for example, to a method and apparatus for video subtitle recognition, an electronic device, and a storage medium. Background technique [0002] At present, video has become the medium of choice for more and more people to transmit information. According to different types, video can be divided into long video, short video or live video. However, no matter what kind of video it is, the subtitle processing method can be adopted to ensure that the video content is clearly communicated to the user, and it is also convenient for the user to extract or identify subtitles through the video for other purposes such as content understanding. [0003] In the related art, the method of identifying subtitles at a specific location is adopted, for example, the video content is a movie clip or a TV series clip, etc., the subtitle is set below the video, and the subtitle is positioned by sett...
