Abstract

The present application discloses a video subtitle positioning method, electronic equipment and a computer storage medium. The video subtitle positioning method includes: acquiring all image frames of a video, and performing text detection on all image frames to obtain the first text of all image frames A collection of frames, wherein the first collection of text boxes includes the text box of each image frame; traverse the first collection of text boxes to obtain the first similarity of the text boxes in the first direction in every two image frames; based on multiple a first similarity, construct the first graph network about the first text box set; cluster the first graph network to obtain a plurality of first sub-networks, and obtain the first sub-network whose number of nodes satisfies the first preset condition Text box for extracting video subtitles in the subnetwork. Through the above method for locating video subtitles, the present application can improve the accuracy of locating video subtitles, and effectively eliminate other interference information in the video.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a video subtitle positioning method, an electronic device, and a computer storage medium. Background technique [0002] Movies and short videos on the Internet are becoming more and more abundant, and watching videos has become one of the main windows for people to entertain and acquire knowledge. The language in which the video is played has become a major obstacle to watching videos from non-native-speaking countries. Picture OCR (Optical Character Recognition, Optical Character Recognition) technology and machine translation technology can be powerful tools to overcome this obstacle. [0003] In the prior art, to identify and translate subtitles in a video, it is necessary to first detect the position of the subtitles in the image. In the existing natural scene text location technology, the temporal and spatial continuity of the subtitles in the video ...
