Abstract

The invention discloses a video caption positioning method, electronic equipment and a computer storage medium. The video caption positioning method comprises the following steps: acquiring all imageframes of a video, and performing text detection on all the image frames to obtain a first textbox set of all the image frames, the first textbox set comprising a textbox of each image frame; traversing the first textbox set, and obtaining first similarity of textboxes in every two image frames in a first direction; constructing a first graph network about the first textbox set based on the plurality of first similarities; and clustering the first graph network to obtain a plurality of first sub-networks, and extracting a textbox of the video caption from the first sub-networks of which the node number meets a first preset condition. Through the video caption positioning method, the video caption positioning accuracy can be improved, and other interference information in the video is effectively eliminated.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method for locating video subtitles, electronic equipment and computer storage media. Background technique [0002] There are more and more movies and short videos on the Internet, and watching videos has become one of the main windows for people to entertain and acquire knowledge. The language used to play videos has become the main obstacle to watching videos from non-native-speaking countries. Image 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 first necessary to detect the position of the subtitles in the image. In the existing natural scene text positioning technology, the temporal and spatial continuity of the subtitles in the video cannot be considered, and ...
